Pelvic Magnetic Resonance Angiography (MRA) — With and Without Intravenous Contrast
An MRI-based exam of pelvic blood vessels that may use IV contrast to evaluate narrowing, blockage, aneurysms, or abnormal vessel patterns.
["Pelvic MRA creates detailed images of pelvic blood vessels to help evaluate circulation and identify vascular abnormalities."]

What is this test?
Pelvic magnetic resonance angiography is an MRI examination focused on the blood vessels in the pelvis. It may include images obtained before and after intravenous contrast is given.
Why might I need this test?
Your clinician may order this test to investigate unexplained leg or pelvic symptoms, poor circulation, or a suspected blood vessel problem. It can also help assess conditions such as arterial narrowing, blood clots, aneurysms, or abnormal connections between blood vessels.
How is the test performed?
You will lie on a table inside an MRI scanner while images are acquired. If contrast-enhanced images are needed, an IV line will be used to administer the contrast. Unlike X-ray and CT scans, MRI does not use ionizing radiation.
How do I prepare for the test?
Follow your imaging center's instructions about eating, drinking, and taking medicines. Tell the care team if you have had a serious reaction to MRI contrast, have kidney disease, might be pregnant, or have an implanted medical device, metal fragment, or other MRI safety concerns.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal findings may indicate narrowed or blocked vessels, a blood clot, an aneurysm, or an abnormal vascular connection. The results may also reveal conditions that are not directly related to the main reason for imaging. Your clinician will interpret the images together with your symptoms, examination, and any other tests.
