Pelvis MRI scan - Risks

Alternative Names

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

What the risks are:

MRI contains no radiation. 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. However, gadolinium can be harmful to patients with kidney problems who require dialysis. If you have kidney problems, please tell your health care provider before the test

The strong magnetic fields created during an MRI can cause heart pacemakers and other implants to not work as well. It can also cause a piece of metal inside your body to move or shift.

Special considerations:

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

CT scan of the pelvic area
Vaginal ultrasound (in women)
X-ray of the pelvic area

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