What is this test?

This is an MRI of the abdomen, the area between the lower chest and the pelvis. Images may be taken before and after an intravenous (IV) contrast agent is given to provide a more detailed view of organs, blood vessels, and other tissues.

Why might I need this test?

An abdominal MRI may be ordered to investigate unexplained abdominal pain, a mass, injury, or suspected disease involving the liver, gallbladder, pancreas, kidneys, spleen, bowel, or nearby blood vessels.

How is the test performed?

You will usually lie on a narrow table that moves into the MRI scanner. The scanner makes loud knocking sounds while it creates images. If contrast is used, a technologist will place an IV line and administer the contrast before taking additional images.

How do I prepare for the test?

Follow the imaging center's instructions and tell the care team about metal implants, prior contrast reactions, kidney disease, pregnancy, or breastfeeding. Remove jewelry and other metal objects when directed, and ask whether fasting is required. Tell the technologist if you feel anxious or claustrophobic.

Frequently asked questions

What does “with and without IV contrast” mean?
The exam includes images before contrast is given and additional images after IV contrast is administered. The contrast can help highlight certain tissues, blood vessels, and areas of abnormality.
Does an abdominal MRI use radiation?
No. MRI uses a strong magnetic field and radio waves, so it does not expose you to ionizing radiation like an X-ray or CT scan.
Why should I tell the care team about kidney disease or prior contrast reactions?
These details allow the imaging team to assess whether contrast is appropriate and plan the examination safely. Most people can receive MRI contrast without problems, but unusual or severe reactions can occur.
