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.
