Magnetic resonance angiography

Magnetic Resonance Angiography (MRA) is a type of MRI procedure used to visualize blood vessels. It employs a powerful magnetic field, radio waves and a computer to evaluate blood vessels and help identify abnormalities or diagnose atherosclerotic disease.

Procedure[edit | edit source]

MRA is a noninvasive test that has the advantage of avoiding the risks of traditional angiography, such as discomfort from a needle stick or the introduction of a catheter. The patient is placed inside the MRI machine and the technician uses a computer to select the area of the body to be imaged. The machine then creates a series of detailed images of the blood vessels.

Uses[edit | edit source]

MRA is used to examine blood vessels in key areas of the body, including the brain, neck, heart, chest, abdomen, pelvis, legs, and feet. It can help to detect, diagnose and aid the treatment of conditions such as aneurysms, atherosclerosis, dissection, stenosis, or vasculitis.

Risks[edit | edit source]

While MRA is generally safe, risks may include an allergic reaction to the contrast material, damage to the kidneys from the contrast material, and the rare chance of a blood clot forming on the tip of the catheter and blocking a blood vessel.
