Abstract：
:MR angiography techniques have recently been applied to evaluation of peripheral vascular disease, both phase-contrast and time-of-flight techniques have been used. Preliminary clinical experience has shown promise in identification of angioplasty candidates, preoperative evaluation in iliofemoral occlusive disease, and identification of tibial run-off vessels.
