imaging of blood vessels using special magnetic resonance (MR) sequences that enhance the signal of flowing blood and suppress that from other tissues. Synonym(s): magnetic resonance angiography

MR angiography

Magnetic resonance angiography, MRI angiography Imaging
A noninvasive method for evaluating the blood vessels of Pts with severe peripheral vascular disease or acute renal failure Pros Less time and cost than conventional catheter angiography without puncture; it is painless, no known complications, much more rapid than cerebral contrast angiography–CCA and allows construction of images in any plane; MRA is useful for imaging of ASHD and dissecting aneurysms of neck and intracranial aneurysms. See Magnetic resonance imaging.
