Run sequences in the order listed.

Sequence	Plane	Comment	Film #
HASTE	Cor and Axial	No fat sat. 5-6mm slices	1
VIBE	Ax	Thru Kidneys	0
3D FLASH	SAG	Use 512 matrix. Try to get effective thickness less than 1.5 mm. Want to include celiac and SMA and renal arteries	0
Timing Run	Ax	Thru kidneys – 1cc at 2cc/sec followed by 20 cc saline at 2cc/sec	0
3D FLASH	SAG	Two measures (with 7 sec between) Second measure may be done on inspiration. Standard timing run.	0
VIBE	Ax	History to prior	1
Do Subtractions		1-Arterial phase – pre-contrast 2 vibe post-pre	0
