Pelvis MRI scan

MRI - pelvis; Pelvic MRI with prostate probe; Magnetic resonance imaging - pelvis

A pelvis MRI (magnetic resonance imaging) scan is an imaging test that uses a machine with powerful magnets and radio waves to create pictures of the area between the hip bones. This part of the body is called the pelvic area.

Structures inside and near the pelvis include the bladder, prostate and other male reproductive organs, female reproductive organs, lymph nodes, large bowel, small bowel, and pelvic bones.

An MRI does not use radiation. Single MRI images are called slices. The images are stored on a computer or printed on film. One exam produces dozens or sometimes hundreds of images.

How the Test is Performed

You may be asked to wear a hospital gown or clothing without metal fasteners. Certain types of metal can cause inaccurate images.

You will lie on your back on a narrow table. The table slides into the middle of the MRI machine.

Small devices, called coils, may be placed around your hip area. These devices help send and receive the radio waves. They also improve the quality of the images. If pictures of the prostate and rectum are needed, a small coil may be placed into your rectum. This coil must stay in place for about 30 minutes while the images are taken.

Some exams require a special dye, called contrast media. The dye is most often given before the test through a vein (IV) in your hand or forearm. The dye helps the radiologist see certain areas more clearly.

During the MRI, the person who operates the machine will watch you from another room. The test typically lasts 30 to 60 minutes, but may take longer.

How to Prepare for the Test

You may be asked not to eat or drink anything for 4 to 6 hours before the scan.

Tell your health care provider if you are afraid of close spaces (have claustrophobia). You may be given a medicine to help you relax and be less anxious. Or, your provider may suggest an open MRI, in which the machine is not as close to the body.

Before the test, tell your provider if you have:

Because the MRI contains strong magnets, metal objects are not allowed into the room with the MRI scanner:

How the Test will Feel

An MRI exam causes no pain. If you have difficulty lying still or are very nervous, you may be given a medicine to relax you. Too much movement can blur MRI images and cause errors.

The table may be hard or cold, but you can request a blanket or pillow. The machine produces loud thumping and humming noises when turned on. You can wear ear plugs to help reduce the noise.

An intercom in the room allows you to speak to someone at any time. Some MRIs have televisions and special headphones that you can use to help the time pass.

There is no recovery time, unless you were given a medicine to relax. After an MRI scan, you can resume your normal diet, activity, and medicines.

Why the Test is Performed

This test may be done if a female has any of the following signs or symptoms:

This test may be done if a male has any of the following signs or symptoms:

A pelvic MRI may be done in both males and females who have:

A pelvic MRI is also often done to see if certain cancers have spread to other areas of the body. This is called staging. Staging helps guide future treatment and follow-up. It gives you some idea of what to expect in the future. A pelvic MRI may be used to help stage cervical, uterine, bladder, rectal, prostate, and testicular cancers.

Normal Results

A normal result means your pelvic area appears normal.

What Abnormal Results Mean

Abnormal results in a woman may be due to:

Abnormal results in a man may be due to:

Abnormal results in both males and females may be due to:

Talk to your provider if you have questions and concerns.


MRI does not use radiation to create images. To date, no side effects from the magnetic fields and radio waves have been reported.

The most common type of contrast (dye) used is gadolinium. It is very safe. Allergic reactions to the substance rarely occur. But gadolinium can be harmful to people with kidney problems who require dialysis. If you have kidney problems, tell your provider before the test.

The strong magnetic fields created during an MRI can interfere with pacemakers and other implants. People with most cardiac pacemakers cannot have an MRI and should not enter an MRI area. Some newer pacemakers are made that are safe with MRI. You will need to confirm with your provider if your pacemaker is safe in an MRI.


Tests that may be done instead of a pelvic MRI include:

A CT scan may be done in emergency cases, since it is faster and most often available in the emergency room.
