Brief 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

Detailed Description:
Contrast Enhanced Magnetic Resonance Angiography MRA is a developing technology that permits the non-invasive evaluation of arterial and venous structures without the need for x-ray based catheter angiography While dramatic progress has been made in the last few years there are still substantial limitations in the accuracy of MRA in judging stenoses and detecting small accessory vessels The purpose of this study is to recruit patients with suspected or documented atherosclerotic disease for evaluation with state-of-the-art MRA using new surface coils new pulse sequence designs novel contrast administration strategies and advanced image processing algorithms This work represents a collaboration between NIH USUHS and General Electric Medical Systems and is supported by a Cooperative Research Agreement CRADA The goal of this pilot study is to improve MRA to the point that it can reliably replace diagnostic x-ray catheter angiography in the evaluation of patients with atherosclerotic disease
