Magnetic Resonance Angiography of Pelvic Vessels with Intravenous Contrast

What is this test?

This is a medical imaging test that uses magnetic resonance imaging, or MRI, to evaluate the major blood vessels in the pelvis. Intravenous contrast helps make the vessels easier to see on the images.

Why might I need this test?

The test may be ordered to investigate reduced blood flow, unexplained pain or swelling, or symptoms suggesting a problem with a pelvic artery. It may also be used to plan a procedure, monitor a known condition, or evaluate the results of another imaging study.

How is the test performed?

You will lie on a padded MRI table while the scanner creates detailed images. A contrast material, commonly gadolinium-based, is given through an intravenous line in your arm or hand, and the pelvic vessels are imaged as the contrast moves through the bloodstream.

How do I prepare for the test?

Follow the imaging center's instructions, and tell the staff about any prior contrast reaction, kidney disease, implanted medical devices, or possibility of pregnancy. Fasting is not usually required unless specifically requested. Remove loose metal items and clothing with metal fasteners before the examination.
