AxT2 TSE/FSEYResp. triggered, BLADE/PROPELLER. If cannot acquire good result run FS AX HASTE/SSFSE.

AxT1 VIBE/LAVA pre-GdYpre-contrast
12
AxT1 VIBE/LAVA post-GdYcare bolus arterial phase: breath hold and start scan immediately after Gd reaches heart
13
AxT1 VIBE/LAVA post-GdYportal phase: begin 10 sec after arterial phase complete (70 sec)
14
AxT1 VIBE/LAVA post-GdYequilibrium phase: start 3-5 min after contrast injection.
15
CorT1 VIBE/LAVA post-GdYwait 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.

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
