Description

One of three methods of angiography utilizing the magnetic properties of tissues and body fluids rather than x-rays to record images. Angiography is a medical test that helps physicians diagnose and treat medical conditions related to blood vessels. In magnetic resonance angiography (MRA), a powerful magnetic field, radio waves and a computer produce the detailed images. MR angiography does not use ionizing radiation (x-rays). MR angiography may be performed without or with contrast material. If needed, the contrast material is usually administered through a small catheter placed in a vein in your arm.
