There’s no special preparation necessary. Continue to take any medication
prescribed by your doctor unless otherwise directed. Patients over 60
or have history of kidney problems, hypertension, or diabetic will require
a Creatinine level blood test results within the last 30 days.
You won’t be allowed to wear anything metallic during the MRI examination,
leave watches, jewelry or anything made from metal at home. Even some
cosmetics contain small amounts of metals, so it is best to not wear make-up.
In order to prevent metallic objects from being attracted by the powerful
magnet of the MR system, you will typically receive a gown to wear during
your examination. Items that need to be removed by patients before entering
the MR system room include:
- Purse, wallet, money clip, credit cards, cards with magnetic strips
- Electronic devices such as beepers or cell phones
- Hearing aids
- Metal jewelry, watches
- Pens, paper clips, keys, coins
- Hair barrettes, hairpins
- Any article of clothing that has a metal zipper, buttons, snaps, hooks,
underwires, or metal threads
- Shoes, belt buckles, safety pins
Before the MRI procedure, you will be asked to fill out a screening form
asking about anything that might create a health risk or interfere with
imaging. You will also undergo an interview by a member of the MRI facility
to ensure that you understand the questions on the form. Even if you have
undergone an MRI procedure before at this or another facility, you will
still be asked to complete an MRI screening form.
Examples of items or things that may create a health hazard or other problem
during an MRI exam include:
- Pacemaker
- Implantable cardioverter defibrillator (ICD)
- Neurostimulator
- Aneurysm clip
- Metal implant
- Implanted drug infusion device
- Foreign metal objects, especially if in or near the eye
- Shrapnel or bullet wounds
- Permanent cosmetics or tattoos
- Dentures/teeth with magnetic keepers
- Other implants that involve magnets
- Medication patch (i.e., transdermal patch) that contains metal foil
Check with the MRI technologist at the MRI center if you have questions
or concerns about any implanted object or health condition that could
impact the MRI procedure. This is particularly important if you have undergone
surgery involving the brain, ear, eye, heart, or blood vessels.
Important Note: If you are pregnant or think that you could be pregnant, you must notify
your physician and the radiologist or the MRI technologist at the MRI
center prior to the MRI procedure.
