ABSTRACT
MRA has progressed from an initial use for brain or solid organs to a feasible technique for vascular study. Even the very peripheral and small diameter vasculature can be evaluated by this radiation and iodinate contrast medium-free technique. Whole-body angio-MR permits rapid, noninvasive, and accurate evaluation of the entire vascular system and can be used for both diagnostic

purposes and monitoring of vascular involvement of peripheral arterial disease, since it offers high enhanced contrast between blood and stationary tissue and fast acquisition times.
