Why is Cardiac MRI imaging helpful?
Angiography is a minimally invasive medical test that helps physicians diagnose and treat medical conditions. Angiography uses one of three imaging technologies to produce pictures of major blood vessels throughout the body. 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 with or without contrast material. If needed, the contrast material is usually injected using a vein in the arm.
