What is this test?

Pelvic MRI is an imaging test that uses a strong magnetic field and radio waves to create detailed pictures of the pelvic organs, muscles, bones, blood vessels, and other tissues. In this test, no intravenous contrast dye is used.

Why might I need this test?

A pelvic MRI may be ordered to investigate pelvic pain, unexplained symptoms, or abnormalities found during another examination or imaging test. It can help evaluate pelvic organs and tissues, including the uterus, ovaries, bladder, rectum, bones, and muscles, and may assist with diagnosing or monitoring certain conditions.

How is the test performed?

You will usually lie on a movable table inside a large MRI scanner. The scanner makes tapping, clicking, or knocking sounds, and you may be asked to remain still or hold your breath briefly while the images are recorded. A staff member will remain in contact with you throughout the examination.

How do I prepare for the test?

Follow the instructions provided by the imaging center. Tell the care team if you have a pacemaker, implanted medical device, metal implants, or a possibility of pregnancy. You may need to change into a gown and remove items containing metal, such as jewelry, eyeglasses, and some electronic devices; fasting is generally not required unless specifically requested.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

The MRI may reveal structural abnormalities involving the pelvic organs, bones, muscles, or surrounding tissues. Findings can be associated with conditions such as cysts, masses, inflammation, infection, injury, or certain bone and soft-tissue disorders, but an abnormal appearance does not by itself establish a specific diagnosis. A radiologist will interpret the images in the context of your symptoms and other examination or test results.

Frequently asked questions

Does a pelvic MRI use radiation?
No. MRI uses magnetic fields and radio waves rather than ionizing radiation.
Why is this version of the MRI performed without contrast?
Many pelvic conditions can be evaluated without injected contrast. The ordering clinician chooses the appropriate protocol based on the clinical question.
Will I feel anything during the MRI?
Most people feel no physical discomfort, although the scanner is noisy and the enclosed space may cause anxiety. Tell the care team if you are claustrophobic or unable to remain still.
