What is this test?

Magnetic resonance angiography, or MRA, creates detailed images of the blood vessels in the right upper extremity, including the arm and hand. It may be performed with and without intravenous (IV) contrast to assess blood flow and the appearance of the vessels.

Why might I need this test?

Your clinician may order this test to investigate reduced circulation, numbness, coolness, weakness, or pain in the right arm or hand. It can also help evaluate a suspected blood clot, narrowing, aneurysm, or other abnormality of an upper-extremity vessel.

How is the test performed?

You will lie on a scanning table while the scanner images the right arm and hand. A blood-pressure cuff may be placed on the arm to help assess circulation, and IV contrast may be given through a vein if the examination includes contrast-enhanced images. The test does not use ionizing radiation.

How do I prepare for the test?

Tell the imaging team about any metal implants, prior reaction to MRI contrast, kidney disease, or possible pregnancy. Remove loose metal objects and follow the facility's instructions; fasting is usually not required unless specifically requested.

Frequently asked questions

Is MRA the same as a standard MRI?
MRA is a specialized MRI technique that focuses on blood vessels rather than the surrounding soft tissues. It uses magnetic fields and radio waves to show vessel anatomy and blood flow.
Does the test use radiation?
No. MRA does not use ionizing radiation, although IV contrast may be used for part of the examination.
What if I am allergic to contrast or have kidney disease?
Tell the imaging team before the test so they can review the allergy, kidney function, and other risks. The team will decide whether contrast can be used safely and whether an alternative examination is needed.
