Contrast Enhanced Resonance Angiography (MRA) in the Diagnosis of Atherosclerotic Disease: A Pilot Technical Development Study
In Brief
An observational study for Atherosclerosis. Completed, across 1 site.
Detailed Summary
Magnetic Resonance Angiography (MRA) is a method used to evaluate arteries and veins without the use of invasive catheters or x-rays (radiation). MRA technique has been continuously improving and has become more accurate at diagnosing problems of narrowing in blood vessels. However, MRA has a difficult time detecting narrowing in small blood vessels, limiting its use to large arteries. The purpose of this study is to recruit patients diagnosed with or suspected of having, atherosclerosis (hardening of the arteries) to participate in a series of new state-of-the-art diagnostic tests using MRA. This study is a combined effort between the National Institutes of Health (NIH), Uniformed Services University of the Health Sciences (USUHS), and General Electric Medical Services and is supported a Cooperative Research Agreement is to (CRADA). The goal of this study is to improve MRA to the point that it can reliably replace diagnostic x-ray catheter angiography in the evaluation of patients with atherosclerosis.
