MRI (Magnetic Resonance Imaging)

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 hydrogen 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 or require additional space.

Preparing for Your Procedure

What to Expect During the Procedure

You will be asked to change your clothes to remove anything with metal snaps or zippers. You will be required to change into a hospital gown and to remove all metallic or magnetic items, jewelry and credit cards.

An IV may be placed in your arm if your provider has ordered an exam requiring injection of MRI contrast. 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. 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 images are being taken. We will provide earplugs or headphones to dull the sound. We also provide a selection of music for you to listen to via online music streaming. The exam is usually completed within 45-90 minutes, depending on the part of the body being scanned.

When will I get the results of the scan?

Your scan will be read by a radiologist and the report will be sent to your provider. Your provider will contact you with the results and answer any questions you may have. You also have online access to your results via your Queen’s MyChart account.
