Cardiac-triggered and segmented two-dimensional MR angiography of peripheral arterial occlusive disease. A pictorial...

Magnetic resonance (MR) angiography has been shown to be an important technique to image the vasculature of the lower extremities. The two-dimensional (2D) time-of-flight technique has evolved as the standard method of MR angiography used to examine patients with peripheral arterial occlusive disease (PAOD). There is evidence that cardiac triggering substantially improves the quality of 2D time-of-flight angiography. In this pictorial essay, we describe PAOD, show the results of this nonintrusive angiographic technique, and provide a current overview of the interventional and surgical management of PAOD.
