How do I prepare for a MRI?

  • Some scans require you to fast, while some scans require no preparation at all. MRI may be performed in conjunction with a CT scan or plain Xray.
  • Inform the staff if you have any existing medical conditions, metal implants and/or electronic device in your body.

What can I expect during my appointment?

You will be asked to changed into an examination gown, a locker will be provided for you to store your personal belongings.

The MRI scanner consists of a circular magnet with a padded scanner couch table (much like a donut). You will lie face-up on the couch table, and the radiographer will fine tune your position. The couch table will then move into the scanner, and you will need to remain as still as possible so as to obtain the best image quality.

The radiographer will be monitoring the progress of the examination from an adjacent room with a clear view of the scanner, and will be ready to render any assistance you may require.

If a dye injection is used, the IV will be removed from your arm before you go home. Allergic reaction from the gadolinium dye is extremely rare. However, should you experience symptoms such as rash, hives or shortness of breath, please notify our technologist immediately if you are still at our centre, or call your doctor or head to the nearest hospital if you have left our imaging centre.
