MRI of the Abdomen/Pelvis

MRI uses strong magnets, so it is important that you notify your doctor of any metal that may be implanted into your body. Jewelry should be left at home. If required, you’ll be asked to remove your watch, hearing aid, and other metal objects. Some makeup also contains traces of metal, so you might have to remove that, too. Braces and fillings typically aren’t a problem. You will be asked to change into a gown. Many clothing items contain metals that could potentially heat up and cause burns. Gowns are provided as well as secured lockers for valuables.

Notify your technologist if you have:

• Any prosthetic joints, such as hip and/or knee
• A heart pacemaker, defibrillator or an artificial heart valve
• An intrauterine device (IUD)
• Any metal plates, pins, screws, or surgical staples in your body
• Any previous brain surgery
• Tattoos and permanent make-up
• A bullet or shrapnel in your body, had metal removed from your eye or ever worked around grinding metal
• Any possibility that you may be pregnant or suspect you may be pregnant
• Claustrophobia and require a sedative. Please ask your referring physician to prescribe one for you

In many cases, patients with a pacemaker cannot have an MRI (your technologist can verify if you have a ‘safe’ pacemaker). Metal used in orthopedic surgery poses no risk during an MRI (in most cases). You will also be asked if you have ever worked with metal. If there is a possibility of metal shrapnel in the eyes, you will be asked to do an x-ray prior to the MRI.

Some scans require the patient to receive an injection of gadolinium: a contrast medium. If this is the case, it will be discussed with you before the procedure. This contrast medium has a lower risk of allergic reaction or kidney damage compared to other mediums commonly used for CT scans. The amount of the contrast injected is determined by the patient’s weight.

What should I expect?

MRI is painless. Some patients may experience a “closed in” feeling, although in most cases, our wide- bore MRI scanners have alleviated this reaction. Plan on being with us for a minimum of 30 minutes, depending on the part of the body being scanned.  You will be asked to remain still during the actual imaging process. You will hear loud tapping or thumping during the exam. Earplugs or earphones and your choice of music will be provided, if you choose.

Depending on the part of the body being examined, a contrast material called gadolinium may be used to enhance the visibility of certain tissues or blood vessels. A small needle is placed in your arm or hand vein and a saline solution IV drip will run through the intravenous line to prevent clotting. About two-thirds of the way into your exam, the contrast material is injected.

You may return to normal activities as soon as the scan is complete. The radiologist will determine if there are any areas of concern in the internal organs or bone structures. The radiologist’s interpretation will then be available to your referring physician in approximately 48 hours after the exam. In most cases, your referring physician will discuss the results with you.
