Use head or extremity coil if possibl

Call Body radiologist.

Sequence	Plane	Comment	Film #
true fisp	Ax		0
DB HASTE	Ax	May want to use coronal plane	2
T1	Ax
T2 TSE	Ax	Fat sat is optional.
VIBE
3D FLASH	Cor	With fat sat. (on 1 or 2, use 3D FLASH found in carotid protocol, change parameters to achieve 6-9 sec. scan time)	0
		NO TIMING RUN	0
3D FLASH	Cor	15-25 measures no gap Inject gad at 2 cc sec, followed by 20 cc saline at 2cc/sec	0
VIBE	Ax	1 measure through veins of interest. This can save the case if the venogram doesn’t come out well.	2
SUBS		Subtract first few arterial-pre and last 2-3 postcontrast measures-pre.	0
