MRI

An MRI is a machine with an elongated circular opening and uses a large magnet to create an image. Patients lie on a sliding table that moves them into position within the machine. Without using radiation, an MRI provides radiologists with detailed images of organs and structures within the body. Some MRI procedures require contrast media for best results.

Your MRI may be done with contrast media, which highlights a particular part of your body so that it may be viewed more clearly. Contrast media is a substance injected into your arm. You may be asked to sign a consent form prior to its use. If contrast media is used, you are encouraged to drink plenty of water before and after your test.

Most MRI procedures do not require any preparation prior to your appointment. However, if you have experienced claustrophobia, please discuss this with your physician prior to scheduling the MRI.

Sometimes the MRI room may be cold, so we recommend you wear warm, loose-fitting, comfortable clothes with no metal. Leave your jewelry at home.

Cell phones, wallets, and electronic devices are not allowed in the scan room. The MRI’s powerful magnet can damage these items.

Notify the technologist:

• If you have ever had a reaction to any contrast media
• If you are pregnant or suspect you may be pregnant
   

Before having an MRI, please inform the technologist if you have any of the following:

• Pacemaker or heart valve replacement
• Any type of implanted pump
• Metal plates, pins, metal implants, surgical staples, or aneurysm clips
• Metallic fragments anywhere in the body
• You have permanent eyeliner or tattoos
• You are pregnant or suspect you may be pregnant
• You ever had a bullet wound
• You have ever worked with metal (e.g., a metal grinder or welder)
• You have any body piercing
• You have an intrauterine device (IUD)
• You are wearing a medication patch

Your MRI may be performed on an outpatient basis or as part of your stay in a hospital. Your procedure may vary depending on your condition. Generally, MRI follows this process:

1. If necessary, you’ll be given a gown and asked to remove any clothing, jewelry, or other objects that may interfere with your procedure.
2. If you are scheduled to have a procedure done with contrast, an intravenous line will be started in your hand or arm. Let the technologist know if you feel any discomfort during the injection.
3. You’ll be positioned on a scan table that slides into the MRI’s circular opening. A signal-enhancing coil may be placed on your affected body part.
4. The technologist will be in the adjacent room observing you during your procedure. They can see and hear you at all times, and you’ll have a call button in case you need them.
5. An MRI can be really loud. We’ll give you earplugs or headphones so you can listen to your favorite music.
6. We’ll ask you to remain very still or hold your breath during the MRI. Movement can distort the image and require another scan.
7. Once the scan is completed, we’ll help you off the scan table. Tell your technologist if you experience any dizziness or lightheadedness.
8. If you have an IV line for contrast, we’ll remove it at this time.

If your physician prescribed sedatives for claustrophobia, you will need to arrange for transportation home and avoid driving.

If you notice any pain, redness, and/or swelling at your IV site after you return home following your procedure, notify your physician.

No special type of care is required after a MRI scan. You may resume your usual diet and activities, unless your physician advises you differently. Your physician may give you additional or alternate instructions after the procedure, depending on your particular situation.
