Glial neoplasms: dynamic contrast-enhanced T2*-weighted MR imaging
Knopp EA; Cha S; Johnson G; Mazumdar A; Golfinos JG; Zagzag D; Miller DC; Kelly PJ; Kricheff II
1999 Jun;211(3):791-798, Radiology
PURPOSE: To evaluate the role of T2*-weighted echo-planar perfusion imaging by using a first-pass gadopentetate dimeglumine technique to determine the association of magnetic resonance (MR) imaging-derived cerebral blood volume (CBV) maps with histopathologic grading of astrocytomas and to improve the accuracy of targeting of stereotactic biopsy. MATERIALS AND METHODS: MR imaging was performed in 29 patients by using a first-pass gadopentetate dimeglumine T2*-weighted echo-planar perfusion sequence followed by conventional imaging. The perfusion data were processed to obtain a color map of relative regional CBV. This information formed the basis for targeting the stereotactic biopsy. Relative CBV values were computed with a nondiffusible tracer model. The relative CBV of lesions was expressed as a percentage of the relative CBV of normal white matter. The maximum relative CBV of each lesion was correlated with the histopathologic grading of astrocytomas obtained from samples from stereotactic biopsy or volumetric resection. RESULTS: The maximum relative CBV in high-grade astrocytomas (n = 26) varied from 1.73 to 13.7, with a mean of 5.07 +/- 2.79 (+/- SD), and in the low-grade cohort (n = 3) varied from 0.92 to 2.19, with a mean of 1.44 +/- 0.68. This difference in relative CBV was statistically significant (P < .001; Student t test). CONCLUSION: Echo-planar perfusion imaging is useful in the preoperative assessment of tumor grade and in providing diagnostic information not available with conventional MR imaging. The areas of perfusion abnormality are invaluable in the precise targeting of the stereotactic biopsy

MR of spinal cord ganglioglioma [see comments]
Patel U; Pinto RS; Miller DC; Handler MS; Rorke LB; Epstein FJ; Kricheff II
1998 May;19(5):879-887, AJNR. American journal of neuroradiology
PURPOSE: Our purpose was to describe the MR imaging features in a series of spinal intramedullary gangliogliomas and to compare these findings with the MR features of intramedullary astrocytomas and ependymomas. METHODS: A retrospective analysis was performed of 76 MR examinations in 27 patients with histologically proved spinal ganglioglioma; these were then compared with imaging findings in a representative sample of histologically proved spinal cord astrocytomas and ependymomas. RESULTS: Statistically significant observations regarding spinal gangliogliomas included young age of the patients (mean, 12 years), long tumor length, presence of tumoral cyst, presence of bone erosion and scoliosis, absence of edema, presence of mixed signal intensity on T1-weighted images, and presence of patchy enhancement and cord surface enhancement. A trend (not statistically significant) was noted for holocord involvement and lack of magnetic susceptibility. CONCLUSION: Spinal ganglioglioma can be strongly suspected if MR images reflect the above criteria; however, the ultimate diagnosis still depends on radical resection and appropriate histopathologic investigation

Spinal cord ependymomas: MR imaging features
Fine MJ; Kricheff II; Freed D; Epstein FJ
1995 Dec;197(3):655-658, Radiology
PURPOSE: To assess the magnetic resonance (MR) imaging characteristics of spinal intramedullary ependymomas. MATERIALS AND METHODS: MR images obtained in 25 patients (aged 12-73 years) with proved intramedullary ependymomas were retrospectively reviewed. T1- and T2-weighted images were obtained in all patients. Gadopentetate dimeglumine was intravenously administered in 23 patients; enhanced sagittal and axial T1-weighted spin-echo images were reviewed. RESULTS: All tumors had hyperintense signal on T2-weighted images. In the 23 patients who received contrast material, all tumors became enhanced; enhancement was heterogeneous in 15 patients and homogeneous in eight patients. Twenty tumors had sharply defined, enhanced borders. Nineteen tumors were centrally located in the spinal cord. A hypointense rim on T2-weighted images was noted in five patients. CONCLUSION: Intramedullary ependymomas become enhanced after administration of gadopentetate dimeglumine; the enhanced borders are usually sharply marginated. They are characteristically located centrally in an expanded spinal cord. Hemosiderin is often present at the periphery of cervical ependymomas

Diagnosis of carotid artery stenosis: comparison of 2DFT time-of-flight MR angiography with contrast angiography in 50 patients
Litt AW; Eidelman EM; Pinto RS; Riles TS; McLachlan SJ; Schwartzenberg S; Weinreb JC; Kricheff II
1991 Jan-Feb;12(1):149-154, AJNR. American journal of neuroradiology
Fifty patients underwent 2DFT time-of-flight MR angiography and intraarterial contrast angiography for evaluation of possible carotid atherosclerotic disease. The MR angiography technique employed contiguous axial flow-sensitive (short TR/TE) slices that were reformatted and postprocessed by using a maximum-intensity projection algorithm to provide 16 angiographic views of the carotid arteries. Both studies were independently reviewed by two observers in a blinded manner. Carotid arteries were categorized as normal, mildly stenotic, moderately stenotic, severely stenotic, or occluded. For the 94 carotid arteries available for review, one observer reported a 70% agreement between the two techniques and the second observer reported a 56% agreement (p = .0001). The best correlation was in the severely stenotic category and the worst was in the occluded category. Agreement between observers was 67% for MR angiography and 72% for contrast angiography, which was similar to that between the two techniques. Although not all carotid atherosclerotic disease was visualized equally well, 2DFT time-of-flight MR angiography had a good overall correlation with the 'gold standard' of intraarterial contrast angiography, supporting its use as a screening technique. While further improvements are needed, use of MR angiography as the primary diagnostic tool for many patients with suspected carotid stenosis should continue to increase

Screening protocol for MR imaging of the internal auditory canal
Litt AW; Mirsky P; Berson BD; Kricheff II
1991 Nov-Dec;15(6):930-933, Journal of computer assisted tomography
We have previously shown that 5 mm axial T1-weighted images following Gd-diethylenetriamine pentaacetic acid (DTPA) administration were sufficient as a screening examination of the internal auditory canal (IAC) and cerebellopontine angle cistern in 80% of cases with sensorineural hearing loss. In the remaining 20% of cases 3 mm slices were necessary for confirmation of the diagnosis. To reduce the number of cases requiring the additional examination, we have modified our protocol to include a coronal 'scout' T1-weighted sequence followed by 5 mm axial sections angled through the IACs. Routine axial T2-weighted images of the posterior fossa were also obtained. One hundred eleven patients were studied with this protocol. In all but two of these the 5 mm sections unequivocally provided the diagnosis and in those two cases the coronal images confirmed the diagnosis suspected on the axial study. Three millimeter slices were not necessary in any patient. This three sequence, post-Gd-DTPA protocol, which requires only 12 min of scan time, is recommended as a screening protocol for IAC and cerebellopontine angle disease

Dural "tail" associated with meningiomas on Gd-DTPA-enhanced MR images: characteristics, differential diagnostic value, and possible implications for treatment
Goldsher, D; Litt, A W; Pinto, R S; Bannon, K R; Kricheff, I I
1990 Aug;176(2):447-450, Radiology
Gadolinium-enhanced magnetic resonance (MR) imaging studies of 30 histologically proved cranial meningiomas revealed a linear enhanced structure or 'tail' extending away from the tumor mass along the dural surface in 18 cases (60%). Contrast material-enhanced computed tomographic studies available in 10 of these 18 cases did not depict this structure. Characteristic features of this MR finding were reviewed, and criteria were defined to distinguish this tail from other enhanced structures. To assess the differential diagnostic value of this finding, gadolinium diethylenetriaminepentaacetic acid-enhanced MR studies of a control group of other extraaxial lesions as well as superficial intraaxial tumors that abut the meninges were reviewed. These cases failed to show this MR feature. Pathologic correlation was available in three meningiomas with the finding of a tail, and these demonstrated meningothelial tumor nodules in the samples taken from areas corresponding to the enhanced regions on MR images. This is in agreement with other recent pathologic studies of the dura mater surrounding meningiomas. The authors believe that the linear enhanced structure described may represent tissue containing tumoral nodules. Awareness of this MR sign may be useful in distinguishing meningiomas from other lesions and in planning total resection of the infiltrated dura mater

Potential misinterpretation of cervical spondylosis with cord compression caused by metallic artifacts in magnetic resonance imaging of the postoperative spine
Levitt, M; Benjamin, V; Kricheff, I I
1990 Jul;27(1):126-129, Neurosurgery
Tiny metallic particles produced by the contact of untempered surgical instruments with a diamond drill produce magnetic susceptibility artifacts that can both limit the diagnostic quality of postoperative magnetic resonance imaging of the cervical spine and cause diagnostic error. A case of cervical pseudospondylosis with apparent cord compression due to such an artifact is presented. The source of these metallic particles is considered, and the nature of the susceptibility artifact is discussed

Role of slice thickness in MR imaging of the internal auditory canal
Litt, A W; Kondo, N; Bannon, K R; Kricheff, I I
1990 Sep-Oct;14(5):717-720, Journal of computer assisted tomography
The relative efficacy of post-Gd-DTPA 5 and 3 mm axial T1-weighted images was compared in the detection of lesions in the internal auditory canal and cerebellopontine angle. One hundred twenty consecutive patients were prospectively evaluated with 5 mm axial T1-weighted slices. If these were negative or questionable. 3 mm axial slices were immediately obtained as the next sequence. Eighteen percent of cases were positive and in none of these was the 5 mm study normal. However, in 22 negative cases and two positive cases, a 3 mm study was necessary for confirmation. Five millimeter axial scanning post Gd-DTPA is recommended as the initial study for detection of masses in the internal auditory canal and cerebellopontine angle. Because this study requires fewer acquisitions than 3 mm sections and can be done satisfactorily on low and midfield systems, there are potential time- and cost-saving benefits to this approach

Intracranial hemorrhagic lesions: evaluation with spin-echo and gradient-refocused MR imaging at 0.5 and 1.5 T
Seidenwurm D; Meng TK; Kowalski H; Weinreb JC; Kricheff II
1989 Jul;172(1):189-194, Radiology
Twenty patients with intracranial hemorrhage were examined with magnetic resonance (MR) imaging at 0.5 and 1.5 T within 2 hours on the two imagers for lesions less than 30 days old and within 24 hours for lesions older than 30 days. MR studies included T1- and T2-weighted spin-echo (SE) and T2*-weighted gradient-refocused (GR) pulse sequences at each field strength. The number of lesions identified and the characteristics (ie, signal intensity of the margin, body, and core) of each hemorrhagic lesion were assessed and compared by means of the three pulse sequences at each field strength. Lesion depiction and characterization were superior (P less than .01) at 1.5 T with T2-weighted SE sequences. Improved depiction and characterization of lesions 300 or more days old (P less than .01) accounted for this result. With the GR sequence, depiction and characterization were similar at both field strengths. The GR sequence did not provide significant additional information about hemorrhage at 1.5 T in this series, but it improved depiction and characterization of hemorrhage at 0.5 T

In vitro magnetic resonance properties of CNS neoplasms and associated cysts
Jungreis CA; Chandra R; Kricheff I; Chuba JV
1988 Jan;23(1):12-16, Investigative radiology
Fresh surgical specimens of central nervous system (CNS) neoplasms were analyzed with particular attention to differences between the T1 and T2 values of the solid and cystic components. Delineation of solid tumor from cyst is important, particularly when surgical intervention is planned, since only the solid portion need be excised. Total protein concentration determinations and microimmunoelectrophoresis for protein distribution and characterization also were performed on the fluid specimens. To diagnose a lesion on magnetic resonance based on T1 and T2 measurements, one must first have a catalog of values on which to base that diagnosis. The authors are reporting such values at 0.25 T. In addition, protein analysis of the fluid specimens has shown that the cysts of the CNS associated with CNS neoplasms are, in fact, transudates rather than collections of cerebrospinal fluid (CSF). Their T1 should permit differentiation from solid portions of neoplasms and from non-neoplastic syringohydromyelia

Lumbar spine after surgery: examination with intravenous contrast-enhanced CT
Firooznia H; Kricheff II; Rafii M; Golimbu C
1987 Apr;163(1):221-226, Radiology
Computed tomography (CT) of the lumbar spine without and with intravenous administration of contrast medium was performed in 143 consecutive patients who had previously had spine surgery for disk herniation and had persistent or recurrent symptoms. Fifty-two patients underwent surgical reexploration. It was possible to make the diagnosis of normal postoperative status, disk herniation, or scarring in 31 (60%) of the 52 patients with the use of CT scans without intravenous contrast medium. CT with intravenous contrast enhancement was useful in 12 of the remaining patients (23%). Enhancement of the margins of a herniated disk occurred in 37 (71%) of the patients. There was near-homogeneous enhancement of postoperative scarring in 34 (65%) patients. Intravenous contrast medium was particularly helpful when disk herniation and scarring were both present, by delineating the margins of a herniated disk and enhancing the entire substance of the scar. In symptomatic postoperative patients, CT of the lumbar spine without intravenous contrast medium should be performed initially. If a definitive diagnosis is not established, CT with intravenous contrast enhancement should be considered

Radiologic imaging of symptomatic ligamentum flavum thickening with and without ossification
Stollman A; Pinto R; Benjamin V; Kricheff I
1987 Nov-Dec;8(6):991-994, AJNR. American journal of neuroradiology
Thickening of the ligamenta flava with and without ossification in the thoracic and lumbar regions is a frequent finding on CT scanning; however, it is not widely appreciated as a possible primary cause of compressive cord, cauda equina, and nerve-root symptoms. We present observations from a series of seven patients whose symptoms were caused exclusively or largely by thickened ligamenta flava in the thoracic and lumbar regions. The findings were best demonstrated on myelography. One of our cases had been missed on previous MR, as would be expected with the null signal of calcification. CT scanning necessitates an extended window to ensure discrimination of an ossified ligament from thecal metrizamide. Thickened ligamenta flava are often found in conjunction with degenerative disease and spinal stenosis at multiple levels and should not be ignored as a possible major contributing factor to the patient's symptoms. In addition, those patients with a secondary block from a thickened ligamentum flavum should be studied from above with C1-C2 puncture to rule out other levels of clinically significant disease. Attention to the particular findings of thickened ligamenta flava is important since surgical intervention must involve removal of the entire offending ligament(s); otherwise clinical symptoms may not be relieved

Computed tomography of spinal chordomas
Firooznia H; Golimbu C; Rafii M; Reede DL; Kricheff II; Bjorkengren A
1986 Jan;10(1):45-50, Journal of computed tomography
Computed tomography of 16 spinal chordomas revealed lytic lesions, or lytic and blastic lesions, of 2 or more adjacent vertebrae and a fairly well-delineated soft tissue mass in 16 patients. Intravenous contrast enhancement revealed multiple zones of hypodensity in 5 tumors pathologically proved to contain areas of cystic degeneration. Invasion of the epidural space was noted on computed tomography in 2 vertebral and 7 sacral lesions, and on myelography in 7 vertebral lesions. Computed tomography is ideal for delineation of the soft tissue component of these lesions, detection of sacral lesions at an early stage, planning of surgical excision or irradiation treatment, and detection of recurrence

Intramedullary spinal cord tumors: MR imaging, with emphasis on associated cysts
Goy, A M; Pinto, R S; Raghavendra, B N; Epstein, F J; Kricheff, I I
1986 Nov;161(2):381-386, Radiology
Fifteen magnetic resonance (MR) imaging studies in 16 patients with intramedullary spinal cord lesions were correlated with surgical findings in all patients and with results of intraoperative spinal sonography (IOSS) in eight. Tumor extent was defined accurately in all but two patients by MR imaging; these lesions were found at surgery to have been underestimated by one to two vertebral body segments. Most tumors had lengthened T1 and T2 relaxation times. Intratumoral cysts were detected by MR imaging in one of eight cases, and rostral and caudal cysts were defined in only two of ten cases. The poor detection rate is attributed to poor spatial and contrast resolution. Preoperative MR imaging to define the extent of cord enlargement and IOSS to define cystic structures appears to be the optimal method of tumor management pending our further study

Posttraumatic syrinx formation: experimental study
Cohen, W A; Young, W; DeCrescito, V; Horii, S; Kricheff, I I
1985 Sep-Oct;6(5):823-827, AJNR. American journal of neuroradiology
An experimental study was performed to examine posttraumatic spinal cord cavitation in an animal model by evaluating immediate and delayed computed tomographic (CT) scans obtained after administration of intrathecal contrast material. Four cats underwent midthoracic laminectomy and spinal cord contusion using a standard 400 g-cm model. All animals were studied by CT with intrathecal contrast enhancement before and 4-5 days, 3-4 weeks, and 7-13 weeks after experimental cord contusion. Either metrizamide or iopamidol was used as the contrast agent. Two of the four cats had CT and pathologic evidence of cord cavitation at the site of injury. Another animal had uptake of contrast material into the spinal cord without pathologic evidence of cyst formation, which was believed to represent malacic change. The fourth animal had a normal-appearing cord by both CT and pathologic criteria. Animals that received metrizamide after cord contusion had generalized myoclonic seizures. This did not occur when iopamidol was administered

Computed tomography (CT) has been shown to be an effective noninvasive means of imaging the lumbar spine in patients with suspected disk disease. The clinical and radiographic evaluation, however, of patients with new or recurrent symptoms after surgery for disk disease is fraught with difficulty. This report describes CT changes seen in seven asymptomatic volunteers scanned at various intervals after disk surgery and discusses the implications of these findings

Computed tomography (CT) is an effective non-invasive method of evaluating the lumbar spine in cases of suspected disc disease. In over a 3-year period in a high volume neuroradiologic practice we have observed a number of pitfalls in the diagnosis of herniated nucleus pulposus which may lead to erroneous conclusions and therefore, decrease the overall accuracy of the examination. These pitfalls, and their implications are presented and discussed

CT of lumbar spine disk herniation: correlation with surgical findings
Firooznia H; Benjamin V; Kricheff II; Rafii M; Golimbu C
1984 Mar;142(3):587-592, American journal of roentgenology
Computed tomography (CT) of the lumbar spine was performed with selectively positioned 5-mm-thick axial cross sections to examine each disk level from the top of the neural foramen to the pedicle of the next caudad vertebra. One hundred consecutive patients with 116 surgical disk explorations were reviewed. There was agreement between the CT and surgical findings in 89 patients (104 explorations) in determination of presence or absence of a herniated nucleus pulposus (HNP). Discrepancy occurred in 12 instances (11 patients): two because of incorrect interpretations, five in previously operated patients, three in spondylolisthesis, and two in spinal stenosis. There were 97 true-positives, eight false-negatives, seven true-negatives, and four false-positives. If nine previously operated patients are excluded from the study, then CT was accurate in detection of presence or absence of an HNP in 93% of the disk explorations

Computed tomography of the sacroiliac joints: comparison with complex-motion tomography
Firooznia H; Golimbu C; Rafii M; Kricheff II; Marshall C; Beranbaum ER
1984 Jan;8(1):31-39, Journal of computed tomography
Forty-seven patients with sacroiliac joint abnormalities were examined with computed tomography and conventional complex-motion tomography. Twenty-nine patients had spondyloarthritis. Of the 29, complex-motion tomography detected bone erosions in 16 patients, whereas computed tomography revealed erosions in nine. Computed tomography was more sensitive in detection of joint narrowing, joint widening, osteosclerosis, and intraarticular bony ankylosis. In the remaining 13 patients, computed tomography was the modality of choice in detection of paraarticular soft tissue pathology, such as abscess or tumor, and in detection of the lesions involving the sacral canal and neural foramina

All complications were recorded from the initial 2488 cases studied with digital intravenous angiography (DIVA) at New York University Medical Center. Mechanisms of producing these reactions were categorized into procedure-related, contrast-medium-related, or disease-related. The complications included extravasation of contrast material into the arm (11 patients) and mediastinum (two), acute pulmonary edema (four), hypotension (23), thrombophlebitis (two), and grand mal seizure (one). Recommendations are made that would allow DIVA to be performed more safely

1983 May-Jun;4(3):488-490, AJNR. American journal of neuroradiology
The serial pre- and postoperative computed tomographic (CT) scans of 115 patients entered in the Cooperative Brain Tumor Study between 1975 and 1982 were analyzed in order to define CT prognostic criteria and to test the hypothesis that radical glioma surgery prolongs patient survival. The CT parameters of mass size, associated edema, and intensity of enhancement were quantitated on all scans. Clinical parameters evaluated included gender, age, length of survival, and useful (Karnofsky greater than 30) survival. Data analyses indicated postoperative residual tumor burden was inversely related to length of survival (p less than 0.01). Postoperative associated edema and intensity of image enhancement were also of prognostic value and showed an inverse relation to survival. Younger patients proved more likely than older patients to attain long-term survival. Residual tumor burden of less than 45 mm diameter on postoperative CT scans was associated with 70% chance of long-term survival. These findings support the radical surgical management of glioma

1983 May-Jun;4(3):312-313, AJNR. American journal of neuroradiology
A randomized double-blind study was conducted to compare the radiographic quality and adverse reactions in myelography of the two nonionic water-soluble contrast media, iopamidol and metrizamide. A total of 46 myelograms were obtained, 28 with iopamidol and 18 with metrizamide. Untoward reactions consisted of nausea, headaches, back and leg pain, neuropsychiatric findings, and urinary retention. Iopamidol caused no reactions in 20 of the 28 cases, while metrizamide caused no reactions in only three of 18 cases. Film quality evaluation showed 22 of the 28 studies with iopamidol were judged excellent, whereas only 11 of the 18 metrizamide studies were judged excellent. The results of this study suggest that iopamidol produces better quality studies with fewer and milder adverse reactions than metrizamide

Spinal cord imaging using real-time high-resolution ultrasound
Braun, I F; Raghavendra, B N; Kricheff, I I
1983 May;147(2):459-465, Radiology
The myelographic evaluation of patients presenting with persistent or recurrent symptoms following surgery for an intrinsic spinal cord mass is difficult. Possible symptom-causing processes include tumor recurrence, intramedullary cyst formation, postirradiation effects, arachnoiditis, and spinal cord atrophy. Since tumor recurrence and syrinx formation may require further surgery, while the other entities generally do not, the distinction between these processes is clinically important. The authors have successfully employed commercially available high-resolution real-time ultrasound imaging systems to investigate a group of patients with these persistent or recurrent symptoms after surgery. The bony laminectomy defect provides an acoustic window for viewing intraspinal contents. Ultrasound can accurately differentiate between cystic and solid lesions and can clearly demonstrate whether a spinal cord is enlarged or atrophic

In this study the positron emission tomographic (PET)-18F-2-deoxy-2-fluoro-D-glucose (FDG) technique was used to study both normal aging and senile dementia. The results derived from 15 young normal subjects (mean age, 26 +/- 5 years) and 22 elderly normal subjects (mean age, 66 +/- 7 years) failed to indicate significant metabolic changes associated with age. A group of 24 patients with senile dementia (mean age, 73 +/- 7 years) showed consistent diminutions in regional glucose use relative to the elderly normals. Across all brain regions the diminutions were 17%-24%. There were also significant correlations between the measures of glucose use and the measures of cognitive functioning. Discriminant function classification analysis results indicate that better than 80% classification accuracy can be achieved for individual PET measures. These data suggest a possible future diagnostic use of PET in senile dementia.

Computed tomography and positron emission transaxial tomography evaluations of normal aging and Alzheimer's disease
de Leon MJ; Ferris SH; George AE; Reisberg B; Christman DR; Kricheff II; Wolf AP
1983 Sep;3(3):391-394, Journal of cerebral blood flow & metabolism
Young normal subjects, old normal subjects, and patients with senile dementia of the Alzheimer's type (SDAT) were studied with both computed tomography (CT) and positron emission transaxial tomography (PETT). Increases in ventricular size with both aging and disease were measured. Regional glucose metabolic rate was not affected by age, but was markedly reduced in SDAT patients. These data indicate that in normal aging, structural brain changes may be more salient than biochemical changes. Although both structural and biochemical changes occur in SDAT, the biochemical changes are more marked. The results suggest that PETT is potentially more useful than CT in the in vivo diagnosis of SDAT.

1983 May-Jun;4(3):553-556, AJNR. American journal of neuroradiology
Alzheimer disease is manifested by both widespread and regionally restricted brain changes, some of which have recently been identified in vivo with computed tomography (CT) and positron emission tomography (PET). This is a report of the regional correlation of CT and PET measurements in 19 carefully diagnosed subjects comprising 11 controls and eight patients with senile dementia of the Alzheimer type. Regional CT attenuation values did not discriminate between the two groups, but PET using 18F-2-deoxy-2-fluoro-D-glucose demonstrated significant regional reductions (range, 21%-28%) in glucose utilization in the Alzheimer group. PET measures were also more consistently related to cognitive decline. The correlation between CT structural measures and PET metabolic measures demonstrated consistent relations between widespread PET regions and CT changes in the thalamus, posterior limb of the internal capsule, and temporal lobes. However, CT changes in the frontal white matter, caudate nucleus, and anterior limb of the internal capsule were not related to any regional PET changes. These data support previous findings of temporal lobe involvement in Alzheimer disease and suggest the involvement of structures in the region of the third ventricle.

Intravenous digital subtraction angiography in the investigation of intracranial disease
DeFilipp, G J; Pinto, R S; Lin, J P; Kricheff, I I
1983 Jul;148(1):129-136, Radiology
Eighty-six patients who presented with a variety of intracranial lesions were examined with intravenous digital subtraction angiography (IV-DSA). A grading system was used to evaluate the ability of IV-DSA to answer specific diagnostic questions regarding intracranial tumors, vasospasm following subarachnoid hemorrhage, lesions of the sella, dural sinus occlusion, and post-therapeutic embolization. Eighty-four per cent of the examinations provided clinically useful information. In 15% of the cases limited but useful information was obtained; only 1% of the examinations provided no useful information. We conclude that IV-DSA can routinely provide useful information in the evaluation of the variety of intracranial lesions described above

1983 Nov;149(2):493-498, Radiology
A group of 35 patients with presumptive diagnosis of Alzheimer disease and 29 normal volunteer spouse controls, all over the age of 60, underwent medical and neurologic evaluation, an extensive psychometric battery, and CT scanning. CT ventricular volume was derived for each CT section by algorithm summation of the number of pixels within a user-defined cerebrospinal fluid range. Composite ventricular volume for each patient, obtained by summation of the individual section ventricular volumes, was corrected for brain size by dividing by the sum of the five largest brain section volumes. For the normal group, composite ventricular volume thus derived was 5.2% and for the impaired group 7.5%; the 44% difference was significant (p less than .009). Increasing ventricular volume was significantly associated with increasing severity of cognitive impairment (p less than .05).

Digital intravenous angiography was used for the documentation and evaluation of cerebral vasospasm secondary to acute ruptured aneurysm. Attenuation of vessel caliber and/or generalized poor visualization of intracranial arteries and prolongation of circulation time were observed in seven patients with the acute clinical diagnosis of cerebral vasospasm. Posttreatment intravenous angiography demonstrated improvement in both arterial caliber and circulation time in six patients who responded to medical therapy for vasospasm.

1983 May-Jun;4(3):646-649, AJNR. American journal of neuroradiology
Metrizamide computed tomography (CT) of the spine allows evaluation of the contents and measurement of the size of intracanalicular structures. The relative size (linear and area measurements) of spinal structures can be changed by varying imaging factors or the density of intrathecal contrast material. Two phantoms, one consisting of rods embedded in a plastic cylinder and the other of a vertebral body with a central rod simulating spinal cord, were evaluated with varying imaging factors (window width and window level) and different contrast concentrations within the surround. It was found that wide window widths allowed the most consistent measurements independent of window level, that a window level midway between the CT number of rod and surround would facilitate uniform measurements independent of window width, and that the use of high concentrations of contrast material (high CT number) in the surround, in combination with a wide window width, was most effective in establishing consistent measurements

Acquired immunodeficiency syndrome: cerebral computed tomographic manifestations
Whelan, M A; Kricheff, I I; Handler, M; Ho, V; Crystal, K; Gopinathan, G; Laubenstein, L
1983 Nov;149(2):477-484, Radiology
CT examination of the central nervous system was performed in 19 patients with acquired immunodeficiency syndrome (AIDS). Eighteen patients were homosexuals, and five drug abusers. Parenchymal and meningeal inflammations were seen in patients with intracranial manifestations of the disease. The most common demonstrable lesion in the parenchyma was toxoplasmosis, which produced ring enhancement, solid enhancement, and nonenhancing focal edema. The most common meningeal inflammation was cryptococcosis, which was diagnosed by examination of the cerebrospinal fluid and did not show specific CT changes. It is concluded that toxoplasmosis and cryptococcosis should be the first diagnostic consideration in patients with neurologic findings who have a history of homosexuality and/or intravenous drug abuse and previous unusual infections or anergy. A delayed contrast scan, single or double dose, appears to be the most accurate method of outlining the total extent of disease thereby helping to locate the best biopsy site for pretreatment diagnosis. Empirical institution of toxoplasmosis therapy is recommended in those cases in which CT findings are consistent with toxoplasmosis and the biopsy shows only nonspecific encephalitis. A biopsy of every parenchymal lesion is not considered necessary

Evaluation of patients before transsphenoidal hypophysectomy for large intrasellar mass lesions has required bilateral internal carotid artery angiography. Using intravenous injection of contrast medium, a method has been developed to visualize the parasellar carotid arteries with rapid sequence sequential computed tomographic scanning. In 18 patients, the cavernous segments of the internal carotid arteries were well seen in 27 of 28 instances with technically complete examinations. The vascularity of the mass lesions and vascular encasement was also demonstrated

The value of dynamic scanning
Cohen, W A; Pinto, R S; Kricheff, I I
1982 Mar;20(1):23-35, Radiologic clinics of North America
Dynamic CT is a proven alternative to angiography in the assessment of parasellar lesions. Characteristics of the tumor, such as vascularity or cystic regeneration, are easily demonstrated. Dynamic CT is able to diagnose conclusively an intracranial aneurysm and to follow the therapeutic course after ligation of the carotid artery. The application of dynamic CT to cerebrovascular disease is limited by the lack of subsecond sequencing in fragmentation scans. Its importance in documenting the patency of the cervical internal carotid artery that appears to be occluded angiographically cannot be overstressed

Giant intracranial aneurysms: rapid sequential computed tomography
Pinto, R S; Cohen, W A; Kricheff, I I; Redington, R W; Berninger, W H
1982 Nov;139(5):973-977, American journal of roentgenology
Giant intracranial aneurysms often present as mass lesions rather than with subarachnoid hemorrhage. Routine computed tomographic (CT) scans with contrast material will generally detect them, but erroneous diagnosis of basal meningioma is possible. Rapid sequential scanning (dynamic CT) after bolus injection of 40 ml of Renografin-76 can conclusively demonstrate an intracranial aneurysm, differentiating it from other lesions by transit-time analysis of the passage of contrast medium. In five patients, the dynamics of contrast bolus transit in aneurysms were consistently different from the dynamics in pituitary tumors, craniopharyngiomas, and meningiomas, thereby allowing a specific diagnosis. Dynamic CT was also useful after treatment of the aneurysms by carotid artery ligation and may be used as an alternative to angiographic evaluation in determining luminal patency or thrombosis

Small acoustic neuromas: detection by high resolution gas CT cisternography
Pinto, R S; Kricheff, I I; Bergeron, R T; Cohen, N
1982 Jul;139(1):129-132, American journal of roentgenology
Experience with 81 gas computed tomography (CT) cisternography procedures in 79 patients in searching for acoustic neuroma is reported. Twenty-one tumors, four exclusively intracanalicular, were demonstrated after standard contrast-enhanced CT was negative. Fifty-five examinations were negative; four were inconclusive. The high resolution scanner with digital localization and reconstruction zoom capability greatly improved image detail. In nine of the 12 normal patients examined with it, the intracanalicular bundle was demonstrated. Substitution of carbon dioxide for air greatly reduced the morbidity of acute post-spinal tap headache. The procedure takes 30--45 min and can be performed on an outpatient basis. It is recommended as the procedure of choice when standard CT is negative in subjects clinically suspected of having acoustic neuroma

Microembolization techniques of vascular occlusion: radiologic, pathologic, and clinical correlation
Berenstein, A; Kricheff, I I
1981 May-Jun;2(3):261-267, AJNR. American journal of neuroradiology
Vascular occlusion is described using microemboli of a predetermined size for the treatment of neoplastic conditions with a 'capillary barrier.' Particulated microemboli of either 40--60 micron Gelfoam powder or 200--1,000 micron polyvinyl alcohol foam (PVA) are best. Fluid embolic agents such as silicone fluid are used in lesions without a capillary barrier. The radiographic, pathologic, and clinical results in three patients are described in detail. Microembolization is useful in the treatment of neoplastic conditions for it produces tumor necrosis in addition to hemostasis

Parenchymal CT correlates of senile dementia (Alzheimer disease): loss of gray-white matter discriminability
George AE; de Leon MJ; Ferris SH; Kricheff II
1981 May-Jun;2(3):205-213, AJNR. American journal of neuroradiology
Neuropathologic studies have defined gross anatomic (structural) as well as histologic (parenchymal) changes of senile dementia (Alzheimer disease). This investigation suggests that loss of gray-white matter discriminability by computed tomography (CT) is related to cognitive impairment in this disease. Discriminability is defined as the relative ease of visual differentiation between gray and white tissues. Twenty-six elderly patients with dementia were subjected to extensive psychometric evaluation, a medical and neurologic examination, and CT scanning. Gray and white matter changes were assessed by subjectively evaluating three brain levels, the basal ganglia, the centrum semiovale, and the high convexity, on a five point scale. Quantitated gray and white matter scores were also obtained by sampling CT attenuation values. In addition, CT structural changes were evaluated by previously reported methods. there were significant correlations (P less than 0.05) between the subjectively assessed loss of gray-white matter discriminability at all brain levels and the measures of cognitive decline. At the high convexity level 91% of cognitive measures correlated with loss of gray-white discriminability. In the same patient group no gray-white discriminability correlation with age was demonstrated suggesting that gray-white discriminability does not simply change with age.

Computed tomography evaluations of brain-behavior relationships in senile dementia of the Alzheimer's type
De Leon MJ; Ferris SH; George AE; Reisberg B; Kricheff II; Gershon S
1980 Summer;1(1):69-79, Neurobiology of aging
Neuropathological investigations have demonstrated brain-behavior relationships in senile dementia of the Alzheimer's type (SDAT), but CT studies have not produced consistent findings. We hypothesized that these discouraging results were in part due to limitations in the methods of CT scan evaluations, and to non-homogeneity of patient populations. The present study examined 43 out-patients with the presumptive diagnosis of SDAT using 37 cognitive test measures and 3 independent CT evaluation strategies. The CT methods included a new rank ordering procedure and two previously used techniques, physical measurement and 4-point rating. Highly significant (p less than or equal to 0.01) brain-behavior correlations were attained using the ranking and rating procedures for evaluation of ventricular and cortical pathology. It was found that rank ordering has high interrater reliability and is superior to the other methods for the evaluation of the ventricular system. The physical measurement of the third ventricle is the single most powerful linear correlate of cognitive impairment. Measurement of cortical sulci are of no correlational significance. Multiple regression analyses indicated that global assessments are the best cognitive predictors of both ventricular and cortical pathology. Thus the present study has demonstrated brain-behavior relationships in vivo in SDAT.

White matter buckling: CT sign of extraaxial intracranial mass
George, A E; Russell, E J; Kricheff, I I
1980 Nov;135(5):1031-1036, American journal of roentgenology
The resolution of present day computed tomography (CT) scanners routinely permits discrimination of gray from white matter with delineation of a gray-white matter interface. Superficially situated extraaxial masses usually preserve the gray-white interface and tend to compress and/or buckle adjacent edematous white matter. This does not occur with superficially situated intraaxial lesions and is, therefore, essentially diagnostic of an extraaxial mass. It is postulated that this sign reflects the relative resistance of gray matter to edema in conjunction with the destruction of th gray-white interface by the infiltration of intraaxial lesions. White matter buckling is almost invariably associated with extracerebral fluid collections. White matter buckling is almost invariably associated with extracerebral fluid collections. It is less often discernible in association with meningioma. In a series of 100 consecutive proven meningioma cases, compression and/or buckling of centra white matter was demonstrated in 28, and in 28 (40%) of 70 superficially situated lesions. White matter buckling is diagnostically significant when it occurs. It has been especially helpful in the diagnosis of otherwise atypical superficial masses

Air-CT cisternography and canalography for small acoustic neuromas
Kricheff, I I; Pinto, R S; Bergeron, R T; Cohen, N
1980 Jan-Feb;1(1):57-63, AJNR. American journal of neuroradiology
Disenchantment with the limitations, and in some cases the morbidity, of currently used radiologic techniques for the demonstration or exclusion of small acoustic neuromas prompted development of an examination using small amounts of intrathecal air and computed tomography (CT). A prospective study was designed to evaluate air CT cisternography/canalography, wherein patients with the clinical symptoms of acoustic neuroma but with negative enhanced CT, were evaluated by metrizamide CT cisternography followed by air CT cisternography/canalography. Pantopaque cisternography was then performed as a control procedure. Four patients had surgically proven tumors. In 13 others, accumulated evidence indicated no tumors were present. Results suggest that air-CT cisternography is superior to all other diagnostic methods in defining small acoustic neuromas, and may exclude an intracanalicular lesion without the potential hazards of Pantopaque cisternography or high concentration metrizamide tomocisternography. With air-CT cisternography, there were no errors in this series

Atypical computed tomography features of intracranial meningioma: radiological-pathological correlation in a series of 131 consecutive cases
Russell, E J; George, A E; Kricheff, I I; Budzilovich, G
1980 Jun;135(3):673-682, Radiology
While most intracranial meningiomas have characteristic computed tomographic (CT) findings, a significant number produce atypical images that may lead to a spurious histopathological diagnosis. The authors reviewed 131 consecutive, previously untreated cases of meningioma, all confirmed pathologically. Nine cases (7%) were misdiagnosed initially as malignant lesions based on CT findings alone. Features such as irregular areas of nonenhancing mass and well defined regions of persistent low density were the reasons for misdiagnosis. Close correlation with pathological findings of tumor necrosis, hemorrhage, scarring, and cystic change was noted. An unexpectedly high incidence of necrosis in untreated meningioma is noteworthy

The most common cerebral metastatic lesion is from carcinoma of the lung. Preoperative cranial computed tomography (CCT) with contrast enhancement was performed in 55 neurologically intact patients with a diagnosis of bronchogenic carcinoma; 3 patients (5%) demonstrated cerebral metastasis.

Contrast enhanced CT scan and radionuclide brain scan in supratentorial gliomas
Butler, A R; Passalaqua, A M; Berenstein, A; Kricheff, I I
1979 Apr;132(4):607-611, American journal of roentgenology
The preoperative contrast enhanced CT and radionuclide brain scans of 60 patients with surgically verified supratentorial astrocytomas were evaluated and compared. Results indicated that the mechanisms of contrast enhancement and radionuclide uptake are identical in the detection of supratentorial gliomas. These diagnostic methods apparently mirror the integrity of the blood-brain barrier and therefore can be useful in assessing the degree of malignancy of supratentorial gliomas. However, lesions with an intact blood-brain barrier will be missed with radionuclide imaging. These parenchymal abnormalities and/or the associated mass effect will be detected with contrast enhanced computed tomography. These findings firmly establish contrast enhanced computed tomography. These findings firmly establish contrast enhanced CT as the primary investigate tool in the suspected brain tumor

A presumed new radiological-pathological entity of atherosclerotic subintimal of the carotid artery is described. Subintimal hematomas were found in 12 of 50 (24%) carotid bifurcations during surgery for repeated transient ischemic attacks in a single hemispheric distribution; only 33% were associated with ulcerations. The typical angiographic appearance was a sharply marginated, rounded, eccentric filling defect located near the extracranial carotid bifurcation, although occasionally it may simulate a typical smooth or even ulcerated atherosclerotic plaque. Pathological mechanisms responsible for the hemorrhage into the atherosclerotic plaque resulting in the hematoma are discussed

The accuracy of angiographic diagnosis of carotid artery ulceration was evaluated. Of those carotid bifurcations showing ulceration at surgery, 60% were diagnosed as having ulcers at angiography. Half of the remaining ulcers occurred in smooth, benign-appearing plaques and were too small to be seen at angiography. An incorrect angiographic diagnosis of ulceration was made in 17 of 50 carotid arteries; in most cases this was due to the presence of a subintimal hematoma in the wall of the artery

Computed tomography is the definitive radiologic diagnostic tool in large pituitary adenomas (1.5 cm or greater). Precision radiographic studies, endocrine correlation, and an understanding of the effect of sellar variations on radiographic images can yield a very high incidence of accurate recognition of pituitary microadenomas.

Giant aneurysms involving or adjacent to the circle of Willis exhibit three CT patterns: nonthrombotic, partially thrombotic, and completely thrombotic. Partially thrombotic aneurysms have the most specific pattern, consisting of a 'target' configuration on the post-contrast scan. Ring calcification of the wall or mural thrombus is frequently observed in partially or completely thrombotic aneurysms. Calcification is not seen in nonthrombotic lesions.

Four histopathological indices of malignancy--cellularity, pleomorphism, vascularity, and necrosis--were correlated with the positive-contrast CT scan in 84 patients with pathologically proved astrocytoma. Vascularity and necrosis correlated best with the scan in supratentorial tumors, while vascularity and cellularity correlated significantly with the scan in cerebellar astrocytomas. These findings indicate that the degree of malignancy of a supratentorial astrocytoma can be inferred from the contrast-enhanced scan, but that this is not generally possible with posterior fossa tumors

The preoperative contrast-enhanced CT scan and the radionuclide brain scan of 70 patients with surgically verified supratentorial astrocytomas were evaluated and compared. The results indicate parallel mechanisms of action of contrast enhancement and radionuclide uptake. These diagnostic modalities apparently mirror the integrity of the blood-brain barrier (BBB) and therefore are useful in assessing the degree of malignancy of supratentorial gliomas. However, lesions with an intact BBB will be missed with RN imaging. These lesions and/or the associated mass effect will be detected with contrast-enhanced computed tomography.

A comparison of radionuclide scanning and computed tomography in metastatic lesions of the brain
Bardfeld, P A; Passalaqua, A M; Braunstein, P; Raghavendra, B N; Leeds, N E; Kricheff, I I
1977 Jul;1(3):315-318, Journal of computer assisted tomography
Forty-seven patients with a final diagnosis of brain metastases were studied with both computed tomography (CT) and radionuclide (RN) scanning. Fifty-three percent of these patients also underwent contrast enhanced CT. Radionuclide scanning detected 94% of the cases, while CT without contrast enhancement was positive in 89%. The addition of contrast material to the CT examination increased the total sensitivity of CT to 94% and permitted the detection of two cases that were falsely negative on RN scanning and CT without contrast. With both techniques, lesions in the cerebral hemispheres were detected more readily than infratentorial lesions. Radionuclide scanning was less sensitive than CT without contrast in the detection of multiple metastases. Contrast enhanced CT should be used in all cases of suspected cerebral metastases unless contraindicated

Brain death: I. Angiographic correlation with the radioisotopic bolus technique for evaluation of critical deficit of cerebral blood flow
Korein, J; Braunstein, P; George, A; Wichter, M; Kricheff, I; Lieberman, A; Pearson, J
1977 Sep;2(3):195-205, Annals of neurology
An innocuous intravenous portable radioisotopic test using technetium 99m pertechnetate was employed to demonstrate the deficit of cerebral blood flow associated with brain death. The results are compared to those of bilateral carotid and vertebral angiography in 20 patients. Absence of a bolus tracing from the head in the presence of a control tracing of a bolus from the femoral artery in two successive studies one hour apart reliably correlated with the clinical and electroencephalographic findings signifying cerebral death in comatose, apneic patients. Angiography indicated absence of intracranial circulation in 10 patients. Stasis filling or retrograde emptying of arterial vessels (or both) occurred in 7 patients. There was no evidence of venous filling in any of these 17 patients; all of them had either an absent head bolus or an 'intermediate tracing.' Results indicate that either form of tracing represents a critical decrease of cerebral blood flow. Two other patients had evidence of severely impaired abnormal posterior fossa circulation without angiographic evidence of cerebral circulation; both of these patients had an absent head bolus. An additional patient had an unusually small head bolus, and angiography revealed extravasation of radiopaque material but no evidence of intracranial circulation. We conclude that the bolus technique is a helpful adjunct in diagnosing brain death

Computed tomography demonstrates intracranial neoplasms so clearly that nearly all early work in this field was limited to descriptions of the appearance of various lesions. Only recently have investigators directed their attention to the medical implications of the physical and pathophysiologic phenonmena that characterize this remarkable new technique. This paper will discuss recent work in these two areas and its clinical implications, and will examine the application of computed tomography to the evaluation of the postsurgical and postradiation patient

By its ability to differentiate the densities of various intracranial tissues, computed tomography is an ideal tool to investigate the postoperative course and complications of neurosurgical patients. The most important immediate postoperative complications are intracerebral edema and epidural, subdural or intracerebral hematomas. The extent of surgical resection of neoplasms can also be studied easily by CT. The method of investigation and representative cases are described

The tentorium in axial section. I. Normal CT appearance and non-neoplastic pathology
Naidich, T P; Leeds, N E; Kricheff, I I; Pudlowski, R M; Naidich, J B; Zimmerman, R D
1977 Jun;123(3):631-638, Radiology
Bands of increased density representing the free edges and lateral margins of the tentorium were routinely identified on 100 sequential, normal, contrast-enhanced axial CT scans of good quality. Because the tentorium has a complex shape, the exact configuration of these bands varies with the level and the angle of the CT section. Comparison of CT scans with anatomic specimens permits an understanding of these varying configurations, and provides a means to estimate the position of the tentorium on non-contrast CT studies. The CT manifestations of diverse non-neoplastic diseases including subarachnoid hemorrhage, arteriovenous malformation, venous sinus thrombosis and Dandy-Walker malformation may be understood, in part, in terms of the configuration and density of these tentorial bands

Naidich, T P; Leeds, N E; Kricheff, I I; Pudlowski, R M; Naidich, J B; Zimmerman, R D

Most juxtatentorial lesions may be localized accurately on contrast-enhanced axial section CT scans by use of the opacified tentorial bands. Lesions that lie lateral edge of the diverging bands are supratentorial. Lesions that lie medial to the V-shaped tentorial bands are infratentorial and/or incisural. Flattening of the tentorial border of a lesion helps to identify its location. Use of the tentorial bands identifies transincisural extension of meningioma reliably, but does distinguish well between true transtentorial growth of meningioma and marked upward bulging of the tentorium from purely infratentorial meningioma

Positive and negative contrast myelography in spinal trauma

1977 Apr;123(1):103-111, Radiology
The myelograms of 60 acutely injured patients were reviewed. Positive contrast material (Pantopaque) was preferred in cervical and thoracic trauma manifesting bony deformity, in cervical trauma without bony deformity (in the prone position), in delineating the thoracic spinal cord in the frontal projection, and in lumbar spinal injuries. Negative contrast material (air) was preferred in cervical trauma without bony deformity, to delineate the thoracic spinal cord in the lateral projection and in chronic trauma to demonstrate cord atrophy. An experimental, water-soluble positive contrast material (Amipaque) may show the spinal cord advantageously in both the anteroposterior and lateral projections and may be more extensively used. A protocol has been devised, based on the analysis of the myelographic findings

Though the advent of computed tomography has improved the detection of posterior fossa lesions, there are times when it can not be used to differentiate between an intra- and extraaxial lesion, particularly when the mass is anteriorly located. Base view angiography can be used to make this distinction, accurately localize the lesion, and demonstrate involvement or compression of vital adjoining structures

The difficulty in evaluating the effectiveness of radiation therapy of primary cerebral tumors is well appreciated. Changes in the tumor size and the presence or absence of edema or necrosis during or following treatment cannot be readily evaluated by present noninterventive roentgenographic methods. At New York University Medical Center, computerized (axial) tomography (CT) has been routinely used both before and after radiation therapy with the aim of assessing, by noninterventive means, tumor response, presence or absence of edema, or necrosis. A selected series of patients is presented with correlation of the clinical findings and CT-scan results both before and after therapy. The significance of these findings and their implications in the management of cerebral tumors are discussed

Computerized axial tomography (CAT) is a new, highly accurate technique for studying the skull and intracranial contents. It is rapid enough to be utilized in acute emergencies and safe enough to be utilized for routine serial followups and evaluation of outpatients with equivocal findings. Because CAT can delineate the ventricular system without need for contrast agent, can distinguish clearly between hematoma and edema and can differentiate cystic from solid tumors, it finds wide application in the evaluation of neurological disease

The effect of angiography on the electrophysiological state of the spinal cord. A study in control and traumatized cats
Fox AJ; Kricheff II; Goodgold J; Spielholz N; Tregerman L
1976 Feb;118(2):343-350, Radiology
The tonic vibration reflex (TVR) and evoked cerebral potential (ECP) were used to evaluate the effects of aortic injections of Renografin- 76, saline, and a mixture of sodium and sucrose on the spinal cord in 7 control cats and 12 which were recovering from trauma. Results showed that Renografin-76 produced different toxic effects in control and traumatized spinal cords as measured by the TVR. The disappearance of either ECP or TVR following the Renografin injection in 4 cases exemplifies the enhanced risk of injecting angiographic materials into traumatized spinal cords during recovery. The TVR shows promise as an electrophsiological criterion of minimal toxic effects of angiographic contrast agents on the spinal cord

An angiographic study of the carotid arterial and jugular venous systems in the cat
Kumar, A J; Hochwald, G M; Kricheff, I
1976 Mar;145(3):357-369, American journal of anatomy
Standard techniques for performing carotid angiography in dogs and in man were adapted to the cat in order to study the vascularization of both intracranial and extracranial structures. Venous drainage was examined by venography of selected vessels. The carotid-cerebral and the vertebral-basilar arterial systems of the cat were studied, although no attempt was made to define the territory supplied by each system. In serial angiograms, vascularization of the rete mirabile conjugatum was visualized and distinct arterial and venous retia were delineated. Large facial veins were seen approximately one second after the intra-arterial injection of radio-contrast material. The early filling of the large facial veins appeared to be the result of an artery-to-venous shunt. Contrast material flowed posteriorly in these veins and drained into the venous rete. When contrast material was injected either into the sagittal sinus or retrograde in the external jugular vein, the internal jugular vein was visible in four of ten cats. This vessel drained blood directly from intracranial contents before anastomosis with the vertebral and external jugular veins

Positive contrast ventriculography in cats with experimental obstructive hydrocephalus
Kumar, A J; Hochwald, G M; Kricheff, I; Chase, N
1976 Nov-Dec;11(6):605-611, Investigative radiology
Cerebrospinal fluid pathways were studied in both normal and experimental obstructed hydrocephalic cats by positive contrast ventriculography. Either water soluble or insoluble contrast material was injected into the lateral cerebral ventricles, and radiographs were taken of the head and spinal cord. In the normal cat, the contrast material freely flowed throughout the spinal fluid spaces. The contrast material accumulated in the cisterna magna, and from there extended into the cranial and spinal subarachnoid spaces. In the kaolin-induced hydrocephalic cat, the outlets from the fourth ventricle were obstructed, and direct communication between the ventricular system and the subarachnoid spaces no longer existed. In these cats, the contrast material passed directly down the central canal of spinal cord and its movement was followed throughout the entire length of the canal. At the lower lumbar-sacral regions, the material perforated the cord and flowed into the subarachnoid space. At all levels, the central canal was enlarged and local dilatations were seen extending dorsally

1976 May;119(2):375-383, Radiology
Analysis of abnormalities of the configuration of the anterior inferior cerebellar artery in lateral projection facilitates diagnosis of posterior fossa masses. Cerebellopontomedullary angle lesions frequently cause arcuate posterior-inferior displacements of the rostrolateral artery or reversal of curvature of the ascending segment of the meatal loop. Vermian, hemispheric, intra-fourth ventricular, and suitably situated extra-axial masses alter the plane of the lateral loop of the caudomedial artery. Tonsillar herniation may be detected in patients with hypoplastic or absent posterior inferior cerebellar arteries by analyzing the relationship of the biventral segment of the descending or caudomedial artery to the foramen magnum

Extra-axial posterior fossa masses can be diagnosed reliably by computed tomography (CT) in most cases. Acoustic and trigeminal neurinomas, meningiomas, cholesteatomas, and other extra-axial masses can usually be distinguished from intra-axial masses by asymmetric widening of the basal subarachnoid spaces, bone destruction, continuity of the tumor mass with the tentorium or bone, and more sharply defined margins. Multiple-cut study of the posterior fossa improved visualization of the fourth ventricle and basal cisterns. Interpretation of cisternal changes in association with changes in the fourth ventricle and abnormal attenuation coefficients permits accurate diagnosis of posterior fossa masses

Computed tomography is the method of choice for initial evaluation of patients with potential suprasellar masses. In our experience, CT has proved completely reliable for detecting or ruling out the presence of a suprasellar mass, the direction and degree of parasellar extension, and the presence of any calcific or cystic component of the lesion. When multiple cut CT has been negative, further diagnostic studies have proved unrewarding. When CT has been positive, additional studies have been required in some cases to rule out aneurysm prior to craniotomy

Anatomy of the thalamoperforating arteries with special emphasis on arteriography of the third ventricle: Part I

1975 Jun;124(2):220-230, American journal of roentology, radium therapy, & nuclear medicine
The thalamoperforating arteries are divided into 2 distinct groups, an anterior and a posterior. The PTPAS are retromammillary branches of the precommunicating segments of the posterior cerebral arteries. The PTPAS may be divided into interpeduncular, mesencephalic and thalamic segments and are not directly related to the third ventricle. They are primarily midbrain and thalamic arteries. The main trunk of the PTPA (mesencephalic segment) normally does not undulate, but assumes a characteristically straight configuration. The ATPAS arise from the posterior communicating arteries anterior and lateral to the mamillary bodies. The ATPAS are primarily diencephalic vessels. Interpeduncular, paraventricular (hypothalamic) and thalamic segments may be identified. The major segment of the ATPAS is para third ventricular in location at the level of the massa intermedia

1975 Jun;124(2):231-240, American journal of roentology, radium therapy, & nuclear medicine
A review of vertebral and carotid angiograms in 59 cases of third ventricular pathology demonstrated that the anterior thalamoperforating arteries are affected primarily by obstructive dilatation of the third ventricle, dilatation of the third ventricle secondary to atrophy, intra third ventricular tumors, anterior and para third ventricular tumors, and hypothalamic and thalamic tumors. The posterior thalamoperforating arteries are affected primarily by midbrain atrophy, midbrain tumors, and thalamic tumors. The primary and secondary effects have been outlined. Understanding of the anatomy of the thalamoperforating arteries facilitates localization of the site of obstruction in hydrocephalus, helps differentiate obstructive hydrocephalus from ventricular dilatation secondary to atrophy, permits differentiation between tumoral and non-tumoral dilatation of the third ventricle, aids in the diagnosis and differential diagnosis of intra third and para third ventricular masses including their posterior extent, and facilitates the diagnosis of thalamic, hypothalamic, and midbrain tumors

Radioisotopic bolus technique as a test to detect circulatory deficit associated with cerebral death. 142 studies on 80 patients demonstrating the bedside use of an innocuous IV procedure as an adjunct in the diagnosis of cerebral death
Korein, J; Braunstein, P; Kricheff, I; Lieberman, A; Chase, N
1975 May;51(5):924-939, Circulation
A portable radioisotopic technique was developed to demonstrate cerebral circulatory deficit, as part of a collaborative study to define and diagnose cerebral death simply and rapidly, in comatose, apneic patients with electrocerebral silence. The method involves an intravenous injection of 2mCi of 99mTcO4, and recording time/activity curves over the cranial cavity and a femoral artery simultaneously, using twin probe radioisotope detector equipment. Eight comatose, apneic patients had 142 studies in conjunction with clinical electroencephalographic and other laboratory evaluations. The results indicate that the absence of a bolus tracing from the head, as contrasted to the usual bolus seen is indicative of significant circulatory deficit to the cerebrum. This test may be used as an adjunct in confirming the diagnosis of cerebral death. A normal bolus tracing should be simultaneously observed over a femoral artery and this is used as a control. The method is safe and simple and offers significant information about the irreversibility of cerebral blood flow. Although further studies are indicated, the method appears to be most promising as a fundamental bedside laboratory test in the diagnosis of cerebral death in conjunction with other clinical and laboratory criteria
