Brain MR angiography (MRA) is a medical test that helps Mountain Medical radiologists diagnose medical conditions related to blood vessels in the brain. The procedure can help identify abnormalities, such as aneurysms, as well as arteriovenous malformation (abnormal communications between blood vessels) inside the brain.
MRA does not use ionizing radiation (x-rays). In MRA a powerful magnetic field, radio waves and a computer produce the detailed images. The procedure may be performed with or without contrast material. If needed, the contrast material is usually administered through a small catheter placed in a vein in your arm.
