    Abstract:
    Magnetic Resonance Angiography (MRA) is the newest non-invasive procedure for the evaluation of the vascular system. The basis to obtain images of vessels from Magnetic Resonance (MR) data rely upon the specific signal alteration determined by flowing blood. By using special techniques only these signals are evidenced, with cancelling of the surrounding stationary tissues. Clinical applications are reviewed in this paper. They include: Evaluation of intracranial vessels with important adjunct information to those obtained by conventional MR images; Definition of cerebrovascular disease including the carotid artery with good correlation with Digital Subtraction Angiography (DSA); Evidence of abdominal vessels, with clear imaging of abdominal aortic aneurysms; Definition of renal arteries; although problems exist, the technique may become useful in the future for the screening of renovascular hypertension; Visualization of peripheral vessels; initial results indicate a potential application in the evaluation of peripheral run-off distal to occlusions.
