1	Liver MRI with contrast
2	Indications:	liver lesion characterization; metastatic disease workup; screening for HCC in chronic liver diseases
3	Contrast	type		rate	volume	saline flush
4		Multihance
5
6	Acquisition	sequence	fat sat	comments
7	Cor/Ax	T2 HASTE/SSFSE	N
8	Ax	T2 TSE/FSE	Y	Resp. triggered, BLADE/PROPELLER. If cannot acquire good result run FS AX HASTE/SSFSE.
9	Ax	T1 GRE IN/OPP	n/a
10	Ax	DWI	n/a	B value 800
11	Ax	T1 VIBE/LAVA pre-Gd	Y	pre-contrast
12	Ax	T1 VIBE/LAVA post-Gd	Y	care bolus arterial phase: breath hold and start scan immediately after Gd reaches heart
13	Ax	T1 VIBE/LAVA post-Gd	Y	portal phase: begin 10 sec after arterial phase complete (70 sec)
14	Ax	T1 VIBE/LAVA post-Gd	Y	equilibrium phase: start 3-5 min after contrast injection.
15	Cor	T1 VIBE/LAVA post-Gd	Y	wait 15-20 sec to recover breath, then run
16	Comments:	care bolus: coronal fast gradient refocused sequence to trigger arterial phase at the moment contrast reaches the heart. Patient must hold breath at this moment and arterial phase run immediately.

20	Liver MRI without contrast
21	Indications:	liver lesion characterization; metastatic disease workup; screening for HCC in chronic liver diseases
22	Comments:	contrast strongly preferred - if non-contrast study ordered, indication should be reviewed by radiologist
23	Acquisition	sequence	fat sat	comments
24	Cor/Ax	T2 HASTE/SSFSE	N
25	Ax	T2 TSE/FSE	Y	Resp. triggered, BLADE/PROPELLER. If cannot acquire good result run FS AX HASTE.

34	Liver MRI with Eovist
35	Indications:	suspect FNH (focal nodular hyperplasia); metastatic workup; cirrhosis screening; biliary reconstruction, bile leak
36	Comments:	Eovist will be specifically requested. If unsure call radiologist.
