Magnetic Resonance Angiography for Peripheral Arterial Disease (PAD)
Study Details
Study Description
Brief Summary
The purpose of this study is to compare the difference between two magnetic resonance imaging (MRI) techniques for visualizing arteries. The study hypothesizes that one method that relies upon imaging flowing blood in the pelvic and leg arteries will not be as accurate or efficient as injecting a safe imaging agent to change the appearance of the blood on the MRI. Both methods will be compared with Digital Subtraction Angiography (DSA).
