What is MRI?

An MRI is a test that creates images of the body using radio waves along with large powerful magnets. No radiation is used for this test.

An MRI scan looks at the soft tissue, muscles, tendons, ligaments, nerves, joints, brain and other internal organs of your body.

How should I prepare for an MRI scan?

Inform your doctor, as well as the technologist if you have or had any of the following:

• aneurysm clips
• metal pins
• metal in eyes
• hearing implants
• metal plates
• cardiac pacemaker
• chance of pregnancy
• recent tattoos
• claustrophobia (may require medication)
• recent surgery within the last 6-8 weeks

If you take medications for claustrophobia, you must arrange for someone to drive you home after your MRI.

Take off all METAL objects, electronic or mechanical devices, hearing aids, watch, jewelry, wallet, etc… A locker is provided for your belongings.

Medication patches will have to be taken off for the MRI so bring an extra patch to put on after your scan.

For a MRI of the bile ducts (MRCP), do not eat or drink anything at least 4 hours before the exam.

You must arrive 30 minutes before your appointment time and register in the MRI department located on level zero (same level as the cafeteria).

What can be expected during an MRI scan?

You will be asked to fill out an MRI questionnaire and change into hospital scrubs. This will be a good time to ask any questions you may have.

The technologist will take you into the MRI suite and lie you down on a table. During the MRI, this table will move in and out of the magnet. (doughnut shaped tunnel).

For the MRI scan, a device called a coil is required to create images. The technologist puts the coil on the area the doctor wants to see.

An MRI can be very loud so the technologist will give you ear plugs or head phones with music. You will be able to speak to the technologist if you need to.

You must stay very still during the MRI scan.

You may also be given an I.V injection of “dye” (contrast agent) called gadolinium, to make it easier for the radiologist (x-ray doctor) to see parts of your body. It is important for you to drink a lot of fluid after your scan to flush the “dye” out of your system.

How long will the scan take?

30-90 minutes depending on the area being scanned.


Please note that the technologists are unable to give test results. Your doctor will receive a copy of the report within approximately 1 week. If you have any questions, concerns or if you are unable to keep your appointment, please do not hesitate to call the MRI booking office at 742-3542 ext 706 or toll free 1-877-742-2571
