Magnetic Resonance Angiography (MRA) of Pelvic Vessels, With or Without Intravenous Contrast

Published: August 9, 2026Updated: August 16, 2026

Pelvic MRA uses magnetic resonance imaging to examine blood vessels in the pelvis. It may be performed with or without intravenous contrast to evaluate blood flow and identify vessel abnormalities.

What is this test?

Magnetic resonance angiography, or MRA, is an imaging test that uses a strong magnetic field and radio waves to create detailed pictures of blood vessels. When performed in the pelvis, it evaluates the arteries and veins that supply or drain the pelvic organs.

Why might I need this test?

Pelvic MRA may be ordered to investigate symptoms such as pelvic pain, leg swelling, or reduced blood flow. It can also help evaluate suspected narrowing, blockage, aneurysm, vascular malformation, or the blood supply to a pelvic mass.

How is the test performed?

You will lie on a table inside an MRI scanner while images of the pelvic blood vessels are taken. If contrast is used, it is given through an intravenous line, and additional images are obtained after it is administered.

How do I prepare for the test?

Follow the imaging center's instructions, as fasting may or may not be required. Tell the care team if you have implanted devices, metal in your body, a previous contrast reaction, kidney disease, or possible pregnancy before entering the scanner.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may indicate narrowing or blockage of a pelvic vessel, an aneurysm, dissection, or an abnormal connection between arteries and veins. Changes in blood flow can also help assess the vascular supply of pelvic organs or masses. Results should be interpreted by your clinician in combination with your symptoms and other imaging or laboratory tests.

Frequently asked questions

Does pelvic MRA use radiation?
No. MRI-based angiography does not use ionizing radiation, unlike a CT angiogram.
Why might intravenous contrast be used?
Contrast can make blood vessels and areas of altered blood flow easier to see. The radiologist will determine whether contrast is appropriate based on the requested examination and your medical history.
What if I am pregnant or have kidney disease?
Tell the imaging center before the examination. The care team will review the reason for the study, whether contrast is needed, and any potential risks to you or the pregnancy.
