The clinical role of PET and PET/CT, in both oncology as well as cardiology, encompasses the core of Dr. Mourtzikos? primary interests in diagnostic imaging. More specifically, evaluating and developing advanced applications of these modalities in the setting of tumor recurrence surveillance. <br><br>Also, teaching Nuclear Medicine to medical students, residents and fellows is a particularly important aspect of her academic goals. As such, she is involved in presenting lectures and conferences at all levels, as well as mentoring medical students and high school students.<br>Insurance

Initial experience with FDG-PET/CT in the evaluation of breast cancer
Tatsumi, Mitsuaki; Cohade, Christian; Mourtzikos, Karen A; Fishman, Elliot K; Wahl, Richard L
2006 Mar;33(3):254-262, European journal of nuclear medicine & molecular imaging
PURPOSE: We retrospectively reviewed FDG-PET/CT images in patients with breast cancer to determine whether PET/CT improved the level of diagnostic confidence as compared with PET and to compare PET/CT and CT findings at the location of suspected malignancies. METHODS: The study included 75 patients with known breast cancer. The initial PET/CT study for each patient was retrospectively reviewed to determine whether improved diagnostic confidence (IDC) regarding lesion localization and characterization was observed with PET/CT as compared with PET alone. PET/CT and CT findings were compared regarding lesion characterization and staging in 69 of the 75 patients, and in the case of discordant findings, comparison with histological or informative follow-up results was also performed. RESULTS: Fifty of the 75 patients exhibited increased FDG uptake in a total of 95 regions. In the comparison of PET/CT and PET, PET/CT resulted in IDC in 30 (60%) of these 50 patients and in 52 (55%) of the 95 regions. In the comparison between PET/CT and CT in 69 patients, PET/CT demonstrated a significantly better accuracy than CT (P<0.05). PET/CT showed definitely positive findings in 60 regions with malignancies, among which CT exhibited positive findings in 43 (72%). PET/CT and CT accurately staged 59 (86%) and 53 (77%) of the 69 patients, respectively. CONCLUSIONS: PET/CT added incremental diagnostic confidence to PET in more than 50% of patients and regions with increased FDG uptake. PET/CT accurately detected more regions with malignancies than did CT. This initial evaluation suggests that PET/CT is preferable to PET or CT in the diagnosis of breast cancer

"USA-Fat": prevalence is related to ambient outdoor temperature-evaluation with 18F-FDG PET/CT
Cohade, Christian; Mourtzikos, Karen A; Wahl, Richard L
2003 Aug;44(8):1267-1270, Journal of nuclear medicine
Increased (18)F-FDG activity in fatty tissue has previously been reported with PET/CT. We previously named this activity uptake in supraclavicular area fat ('USA-Fat'). We and others have speculated that this uptake exists in metabolically active brown adipose tissue (BAT). Such tissue might be expected to have varying metabolic activity depending on the ambient temperature. The purpose of this study was to evaluate the frequency of USA-Fat and its relationship to the outdoor temperature. METHODS: Between July 2001 and June 2002, 1,017 consecutive whole-body scans were obtained with a PET/CT scanner and (18)F-FDG for clinical patients. PET images were reviewed for the presence of USA-Fat. RESULTS: USA-Fat was observed in 68 scans obtained from 62 patients (51 female and 11 male). The incidence of USA-Fat was highest, at 13.7%, in January through March, while outside temperatures were low, and was significantly lower, at 4.1%, during the rest of the year. CONCLUSION: The incidence of USA-Fat is clearly increased during the cooler period of the year. This finding suggests that stimulation by cold temperatures increases the frequency with which USA-Fat occurs, supporting underlying BAT as the etiology for this activity
