MRI (Magnetic Resonance Imaging)

An MRI, also known as Magnetic Resonance Imaging, is a safe and effective way for Queen’s Imaging specialists to see inside your body. The MRI provides a view of living tissue without the use of any radioactivity or X-rays.

The MRI scanner produces a powerful magnetic field that causes water particles within your body to
produce a signal. A computer assembles the signals into detailed images of the structure and functions
of your body.

Queen's Imaging also has a wide bore MRI for patients that are claustrophobic are require additional space.

Preparing for Your Procedure

  • Transportation: No special preparations are required for this test. You will be able to drive home after this test.
  • Food and Drink: You may eat normally unless other instructions have been given.
  • Medications: You may take any prescribed medications unless other instructions have been given.

What to Expect During the Procedure

An MRI is usually completed in 45 minutes or less, depending on the part of the body being scanned.

Prior to the procedure, you will be asked to change your clothes to remove anything with metal snaps or zippers, as well as remove all metallic or magnetic items such as jewelry and credit cards. You may wear your own metal-free clothing, or change into a patient gown.

You will lay down on a padded table which will move gently through the MRI scanner’s opening. The table will stop moving when the area of your body to be imaged is in the center of the scanner’s magnet. You will feel no discomfort at all but will be asked to hold as still as possible while the images are being taken. Relax and breathe normally. All scanners have an intercom so you can talk to a technologist at any time. Someone is always just a few steps away and happy to answer any questions you may have.

When the scan begins, you may hear a rapid knocking sound while the images are being taken. We will provide earplugs or headphones to dull the sound. We have a selection of music for you to listen to, or you can bring a CD of your own.

Your scan will be read by a radiologist and the report will be sent to your doctor. Your doctor will contact you with the results and answer any questions you may have.
