What is this test?

Magnetic resonance angiography, or MRA, creates detailed images of blood vessels in the abdomen. It may be performed with or without an intravenous contrast agent, depending on the examination and the information your clinician needs.

Why might I need this test?

Abdominal MRA may be ordered to evaluate symptoms such as unexplained abdominal or flank pain, or to assess major blood vessels before a procedure. It can also be used to monitor known vascular conditions.

How is the test performed?

You lie on a movable table while an MRI scanner takes images of the abdominal vessels. If contrast is used, it is given through a small intravenous line in your arm; the scan generally requires you to remain very still and may be noisy and lengthy.

How do I prepare for the test?

Follow the instructions provided by the imaging center, especially whether you should receive or avoid contrast. Tell the care team about kidney disease, prior contrast reactions, pregnancy, implanted devices, metal in your body, and any claustrophobia before the examination.

Frequently asked questions

Is abdominal MRA the same as a routine abdominal MRI?
No. MRA is specifically focused on imaging blood vessels, although the examination may include additional abdominal images.
Does the test require intravenous contrast?
It depends on the protocol. Some MRA examinations use contrast, while others can be performed without it, so confirm the instructions with your imaging center.
Will I need to stay still during the scan?
Yes. Remaining still is important for clear images, and the technician may ask you to hold your breath briefly during certain images.
