1.5 T ULTRA SHORT HIGH FIELD MRI
Magnetic Resonance Imaging ( MRI )

MRI uses large magnets and radio-frequency waves to produce pictures of the body’s internal structures; no x-ray exposure is involved.

How to prepare:

  • If you are not claustrophobic (fear of closed spaces):
    • You will not require any sedation.
    • Eat as usual.
    • Take your medications as usual.
  • If you are claustrophobic:
    • You may ask your doctor to schedule your MRI with sedation (a medication to help you relax).
    • If you take a sedative, you may not eat any solid food for six hours prior to receiving your sedative to avoid nausea. You may have clear liquids (apple juice, jello, black coffee or tea, water) up to two hours prior to your medication time.
    • You may take your regular medications unless your doctor advises against it.
    • For your safety, bring a companion to drive you home.
    • Take your regular medication with sips of water
    • If you do not require sedation, do not request it.

For your safety, anyone undergoing a scan should be free of certain metallic or magnetic items. Inform the MRI staff if you have any metallic implants or any metal under the skin. Most metallic implants, such as sternal wires and mediastinal clips used for heart surgery, pose no problem. However, some conditions may make an MRI inadvisable. Tell your doctor if you have any of the following conditions:

  • implanted pacemaker or defibrillator
  • cerebral aneurysm clip (metal clip in a blood vessel in the brain)
  • pregnancy
  • implanted insulin pump, narcotic pump or implanted nerve stimulators (TENS) for back pain
  • metal in the eye or eye socket
  • cochlear (ear) implant for hearing impairment
  • some stents - while most stents are safe, some stents may not be (for example, the Zenith AAA Endovascular Graft)
  • Wear a shirt or blouse that can be easily removed. Women should wear a bra that can be easily removed prior to the examination. You may wear metal-free pants, such as sweatpants with elastic bands, during the test. A gown will be provided. Leave these items at home, if possible:
    • belt buckles
    • metal zippers
    • snaps
    • watches
    • wallets with bank or credit cards with magnetic strip

What to expect:

  • An MRI technologist will prepare you for your scan.
  • You will change into a hospital gown.
  • The MRI scanner unit is a long tube that scans the body as you lie on a platform bed. It is fully lit and ventilated, and open at both ends. An intercom system allows you to talk to the scanner operators during the test. You will lie on your back on the scanner bed, with your head and legs elevated for comfort. During the exam, you will be asked to lie as still as possible. The technologist will ask you to hold your breath periodically for short periods in order to reduce blurring of the images from breathing motion.
  • For contrast exams, an intravenous (IV) line will be inserted into a vein in your arm for non-iodine based contrast (dye) administration.
  • During scanning, you may hear loud banging noises, which can be muffled with headphones or earplugs you will receive before scanning begins.

The MRI scan takes about 25 to 45 minutes, depending on the extent of the imaging needed.

After the procedure:

  • If you received sedation:
    • The MRI nurse will give you instructions on when you can eat, drink and return to normal activities.
    • A companion should drive you home.
  • If you did not receive sedation, you may resume your usual activities and normal diet immediately.
  • Your physician will discuss the results of your test with you.
