Important Things to Know About MRI

Doctors use magnetic resonance imaging (MRI) to find diseases or abnormalities in the body without using X-rays. MRI uses a magnetic field and radio waves to create detailed images of the body. MRI is non-invasive and painless and most scans require fewer than sixty minutes to complete.

During an MRI scan, you lie on a cushioned table that moves into the scanner. An injected contrast agent may be used. MRI contrast agents rarely cause allergic reactions.

Patient Instructions

Arrive 15 minutes early to complete paperwork. Inform your referring physician if you have ever experienced claustrophobia. If necessary, your doctor can prescribe a mild sedative before your appointment. If you receive medication, bring someone to drive you home.

  • Contact us to find out if you have any restrictions on what you can eat and drink before your appointment.
  • Take your regular medications prior to your exam.
  • Bring your insurance information, as well as any applicable diagnostic films.
  • Leave valuables at home. No metal objects can be worn during your scan (such as watches, jewelry, keys, or cell phone).
  • You may be asked to wear a hospital gown or your own clothing if there are no metal snaps or zippers.

Notify Our Staff In Advance If You:

  • Have implanted devices
  • Have any serious health problems
  • Have had any surgery within the last eight weeks
  • Have ever had surgery on your brain, ears, eyes, or heart
  • Have metal in your eyes, or work with metals
  • Have a bone or joint replacement or any prosthesis
  • Are or may be pregnant or breastfeeding
  • Weigh more than 300 pounds

Once your scan is complete, you may resume normal activities and diet. If you had a contrast injection, the technologist will give you additional instructions in case of discomfort or delayed reaction.
