What is this test?

Magnetic resonance angiography, or MRA, is an imaging test that produces detailed pictures of the arteries and shows how blood flows through them. Intravenous contrast is given through a vein to improve the visibility of smaller blood vessels.

Why might I need this test?

MRA may be used to evaluate symptoms such as limb pain, numbness, weakness, dizziness, or difficulty walking. It can also be used to check known blood-vessel conditions or plan treatment for a suspected narrowing, blockage, aneurysm, or other vascular problem.

How is the test performed?

You will lie on a table that moves inside a magnetic resonance scanner. An IV line is placed in your arm, contrast is injected, and several sets of images are taken. The scan is painless, but the scanner can be noisy and may make you feel confined.

How do I prepare for the test?

Follow the instructions provided by your care team and tell the imaging staff about any prior contrast reaction, kidney disease, pregnancy, implanted medical devices, or metal in your body. Do not stop medicines unless your clinician specifically tells you to.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may indicate narrowed or blocked arteries, an aneurysm, arterial dissection, or an unusual pattern of blood flow. These findings should be interpreted by a radiologist in the context of your symptoms, examination, and other tests.

Short name

MR angiography (MRA) with IV contrast

Frequently asked questions

Is MRA with contrast the same as a standard MRI?
It uses the same type of scanner, but MRA is specifically designed to image blood vessels and blood flow.
Will I feel the contrast injection?
The injection may feel like a brief pinch or a warm sensation. Serious reactions are uncommon, but tell the staff immediately if you develop itching, hives, swelling, or breathing difficulty.
How long does the test take?
The exact time varies by the area being imaged and the facility's equipment. The care team can provide a more specific estimate before the examination.
