Computed Tomography (also called CAT Scan) is a scan that produces images of your internal organs and structures, which help to diagnose and monitor pain or disease and guide treatment.

While these commonly include scans of the brain, chest, abdomen, pelvis and spine, they can be used to image all parts of the body.

Computed Tomography (CT) allows images to be produced of your internal organs and structures to assist in the diagnosis of discomfort or disease. The CT machine is shaped like a large ring or donut, and produces high quality pictures very quickly. These images can be reconstructed in many ways to give the doctor different viewpoints. The procedure is quite fast, and nothing will touch you during the examination.

The scan will take 5-15 minutes in most cases and in some cases you will be given an injection of a dye (contrast) to assist in detecting abnormalities.

What you need to know


You will be advised of any specific instructions at the time you make your appointment or by your referring doctor depending on the scan. For example, this may include strict preparation instructions the day prior to, and the day of, the scan.


Very few people experience an allergic reaction to contrast, but if you are aware of an allergy, please let us know before your scan. CT imaging does emit radiation, and while our new machines adjust radiation dose to the lowest achievable level (to produce a high-quality scan), if you have concerns about radiation dose, please discuss with your doctor.


The report from our radiologist will be forwarded to your doctor as soon as possible. If there are any urgent findings, a radiologist will notify your referring doctor immediately.
