This sophisticated technique uses a strong magnetic field to produce exquisitely detailed images of the nervous system, musculoskeletal system and pelvis. It also can be used to diagnose certain chest and abdominal disorders. But one of the newest and most exciting uses of MRI is the evaluation of the body's arterial system.
Arteries are vessels which carry blood from the heart to all of the organs and tissues of the body.
But arteries can become narrowed or blocked, which prevents oxygen-containing blood from reaching the organs of the body. The result of this impaired blood supply is damage or even death of the tissues. Either can rupture or bleed, leading to tissue damage or death. Evaluating Arterial Obstruction Of the three techniques for evaluating arterial obstruction, the oldest is arteriography. In this procedure, a catheter is threaded into the blood vessel and a contrast agent or dye is injected.
