Genitourinary Clinical Protocols

Kidney Donor (Regular)

Updated 11/2001

Coil: On the Vision system, use the phased array coil centered over kidneys. On the Symphony system, use the 2-piece body array to cover down to the pelvis.

30 cc Gadolinium contrast (*). This allows for better vein opacification.

Assess the patient’s breath holding capability. If poor capability, give oxygen. If the patient can’t hold his/her breath, call body radiologist.

Run sequences in the order listed.

Sequence	Plane	Comment	Film #
T1 in/out	Ax		2,1
HASTE	Cor	No fat sat. 4-5 mm slices	2
VIBE	Ax	Slab thickness to include kidneys and proximal ureters.	0
3D FLASH	Cor	Try to get effective thickness 1-1.5mm. Keep the slab as small as possible (usually 96mm or less) – you don’t need to include the entire kidneys; just the renal vessels and the roots of the celiac and SMA.	0
Give Lasix		Dose: 10mg (1cc from 10cc vial)
Timing Run	Ax	Thru kidneys – 1cc at 2cc/sec followed by 20 cc saline at 2cc/sec	0
3D FLASH	Cor	Use standard timing formula On Vision: 2 measures (7 sec gap) On Symphony: 3 measures (0, 7 sec gap, 90 sec) Use standard timing formula.	0,1 0,1,1
VIBE	Ax	Hx prior. 1 measure. Run as soon as possible after the FLASH sequences.	1
3D FLASH	Cor	Delayed Urogram	0
Do Subtraction		1-3D FLASH Arterial phase – pre-contrast 2-VIBE post-pre	0
