Purpose

Objective:
Contrast enhanced MR angiograhy has rapidly become a clinically accepted and diagnostically useful tool. MR angiography has not replaced intra-arterial digital subtraction angiography, but rather aids the work-up and diagnosis of spinal vascular lesions. MR angiography has advanced over the past decade to become a useful, non-invasive adjunct to intra-arterial DSA. Initial time-of-flight MR angiography has given way to contrast enhanced dynamic MR angiography.This exhibit aims to illustrate the basic physics of MR angiography, describe the latest technique in contrast enhanced MR angiography, and illusrate spinal vascular lesions as seen on contrast enhanced MR angiography.
