What is this test?

Pelvic magnetic resonance angiography, or MRA, is an imaging test that uses magnetic fields and radio waves to create pictures of blood vessels in the pelvis. It is not a blood or urine laboratory test. The protocol may include two views and may or may not use intravenous contrast.

Why might I need this test?

A pelvic MRA may be ordered to evaluate pelvic blood flow or investigate symptoms such as leg swelling, pain, or reduced circulation. It may also be used to assess the vessels before or after a vascular procedure or in certain situations involving trauma.

How is the test performed?

You will lie on a padded table that moves into a magnetic resonance scanner. The scanner makes loud knocking or clicking sounds. If contrast is used, it is given through a small intravenous line in your arm, and the scan may be repeated after the contrast is injected.

How do I prepare for the test?

Follow the imaging center's instructions about eating, drinking, and taking medicines. Remove jewelry, hearing aids, and other metal items before entering the scanner. Tell the care team if you have a contrast allergy, kidney disease, implanted medical device, or possible pregnancy.

Frequently asked questions

Does pelvic MRA use radiation?
No. MRA uses magnetic fields and radio waves rather than ionizing radiation, which distinguishes it from standard X-ray angiography.
Will I receive contrast dye?
It depends on the ordered protocol. Some pelvic MRA examinations include intravenous contrast, while others are performed without it.
Is the test painful?
The scan itself is generally painless, although the scanner is noisy and the enclosed space may feel uncomfortable. An IV injection may cause a brief cool sensation or mild discomfort.
