Computerized Tomography (CT)

A CT Scan is an imaging test that uses a computer to combine a series of x-rays to create 3D images of the bones, blood vessels, tissues and organs in your body.

A solution sometimes called x-ray dye or contrast may be used to help highlight certain parts of your body to see them more clearly on the images.

A CT scanner looks like a very large doughnut.  You will be lying on a narrow table that will move you in and out of the center of the machine.  Most CT exams are completed in a few minutes.

A CT scanner uses x-rays, therefore before your exam, it is important to let the technologist know if there is a chance you could be pregnant.

Plan to be in the CT Department between 30 minutes and 2 hours. The length of time will depend the exam you are having done and the preparation needed for the scan. Emergency cases and in-patients may be taken ahead of you. We will make every effort to complete your test as soon as possible.

When you come in for your CT scan:

  • Don't wear jewellery. You may need to remove your dentures, hearing aids, hairpins or wigs if we are scanning you above the neck.

Please arrive 15 minutes prior to your appointment to register. When you arrive at the Hospital, please come to the 2nd floor – North Tower and check in at the reception desk.
