What is this test?
Magnetic resonance imaging, or MRI, is a scan that uses magnetic fields and radio waves to produce detailed pictures of organs and tissues. This version examines the abdomen and pelvis and does not use injected contrast dye.
Why might I need this test?
An abdominal and pelvic MRI may be ordered to investigate unexplained pain, a mass, organ injury, infection, inflammation, stones, or other structural changes. It may also help characterize findings seen on another imaging test or monitor the course of a known condition.
How is the test performed?
You will lie on a moving table inside an MRI scanner. The machine makes loud knocking and clicking sounds, and you may be asked to hold very still or use a breath hold during some images. A technologist performs the scan, and a radiologist reviews the pictures.
How do I prepare for the test?
Follow the instructions provided by the imaging center. You may need to avoid eating or drinking for a period, and you should tell the care team if you have metal implants, a pacemaker, claustrophobia, or any possibility of pregnancy. Jewelry, watches, and other metal items are usually removed before the scan.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal findings may reflect conditions involving the liver, kidneys, spleen, bowel, bladder, reproductive organs, blood vessels, or surrounding tissues. Depending on the appearance, results may be associated with infection, inflammation, injury, stones, cysts, or a mass. The radiologist's interpretation should be considered together with your symptoms, examination, and other tests.
