Prepare for Your
Magnetic Resonance Imaging (MRI)

An MRI scan produces pictures of internal body structures. Each exam will take 15 to 45 minutes. Because an MRI uses a magnetic field, there is no risk of radiation exposure.

Prior to your appointment, please let us know if you are nursing or may be pregnant, or if you have:

  • A pacemaker, aneurysm clips, or other metallic implants or devices
  • Had any previous surgeries
  • Transdermal/medication patches
  • Had metal removed from your eyes
  • An intrauterine device (IUD)
  • A gunshot wound

Before the MRI scan:

  • An MDC nurse will contact you 24 to 48 hours prior to your exam to review preparation instructions
  • If you have questions or require more information about your exam, please feel free to contact an MDC nurse at 612.879.1528 (8 am - 4 pm)
  • Please arrive 30 minutes early for registration verification
  • Please bring previous imaging studies with you to your exam (MRI or CT reports and images)
  • You will be asked to change into a gown
  • Remove any jewelry, hearing aids, eyeglasses, or removable dental work
  • If you are having a non-enhanced scan (no contrast medium), eat and drink as you normally would
  • If you are having an enhanced scan (with contrast medium), do not eat or drink for one hour before the scan

During the MRI scan:

  • A two-way intercom will allow you to talk to your technologist any time during the exam
  • If you are having an enhanced scan, a contrast medium will be injected through an IV into your arm or hand
  • You will be asked to lie still to prevent the images from blurring
  • While the noise experienced during an MRI varies depending on the scan sequences, below is one example of what you may hear

Following the MRI examination, a radiologist analyzes the images and sends a report to your doctor, who will then discuss the results with you.
