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 #
HASTE	Cor	No fat sat. 5-6mm slices	1
HASTE	Ax	No fat sat. 5-6 mm slices	1
VIBE	Ax	Slab thickness to include entire liver, kidneys and mass	0
Timing Run	Ax	Thru kidneys – 1cc at 2cc/sec followed by 20 cc saline at 2cc/sec	0
3D FLASH	Cor	1 measure (0 sec), post contrast only is needed on follow up Use standard timing formula.	0
VIBE	Ax	Hx prior. Timing: Cover entire liver 2 measures (70, 180 sec)	1
