Magnetic Resonance Angiography, Abdomen — With and Without Intravenous Contrast

What is this test?

Abdominal magnetic resonance angiography, or MRA, is an MRI examination that creates detailed images of the abdominal aorta and major branches, including arteries supplying the kidneys and intestines. Images may be acquired before and after intravenous contrast is given.

Why might I need this test?

This test may be ordered to investigate suspected narrowing or blockage of abdominal blood vessels, an aneurysm, unexplained abdominal symptoms, or a condition affecting kidney or intestinal blood flow. It can also help plan treatment or monitor certain vascular conditions.

How is the test performed?

You lie on a table inside an MRI scanner while images of your abdomen and blood vessels are recorded. IV contrast may be injected through a vein, and the scan may include images both before and after contrast. The examination usually takes 30 to 60 minutes, although timing varies.

How do I prepare for the test?

Tell the imaging team if you have kidney disease, a prior reaction to MRI or IV contrast, are pregnant or may be pregnant, or have implanted devices such as a pacemaker. Follow the facility's instructions about eating, drinking, medications, and metal objects, and allow enough time to arrive early.
