I look for 2D, or 2D TOF, (usually the non con portion), 3D, 3D TOF, (usually contrast portion, also angiographic MIPS of the area (COW, carotids).
Any of those alone or together documented for an MRA.
MRI MRA sequences are not cut and dry like CT.
Seimens, Philips, GE all have different angiographic software with different names for the angiographic sequences.
I am close to the MRI scanner, so I am frequently asking the techs to help me.
