What is this test?

Magnetic resonance angiography, or MRA, creates detailed images of the arteries that supply blood to both upper extremities. Your care team may order it with or without intravenous contrast, depending on the information needed.

Why might I need this test?

This test may be used to investigate reduced blood flow, numbness, coolness, color changes, or weakness in an arm or hand. It can also help evaluate suspected arterial narrowing, blood clots, aneurysms, or congenital blood-vessel abnormalities.

How is the test performed?

You will lie on a padded table that moves into a large MRI scanner. The scan typically takes several minutes and may be repeated. If contrast is used, it is given through a small intravenous line in a vein.

How do I prepare for the test?

Follow the imaging center's instructions and tell the staff about any implanted devices, metal objects, prior contrast reactions, kidney disease, or possible pregnancy. You may need to remove jewelry, watches, hearing aids, and other items containing metal.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may indicate narrowing or blockage of an upper-extremity artery, an aneurysm, or another blood-vessel abnormality. Results are interpreted together with your symptoms, examination, and other tests, so a radiologist will explain their clinical significance.

Short name

Upper Extremity MRA

Frequently asked questions

Is an upper extremity MRA the same as a regular MRI?
An MRA is a specialized MRI technique that focuses on blood vessels. It does not use ionizing radiation and may or may not require intravenous contrast.
Does the MRA require a blood draw?
A routine blood draw is not required. If the study includes contrast, the contrast is administered through an intravenous line.
Will I feel anything during the MRA?
The scanner can feel cramped and may make knocking or vibrating noises, but the procedure itself is generally painless. A technologist will guide you and allow you to communicate during the scan.
