Computed tomography is commonly referred to as a CT scan. A CT scan is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce images of the inside of the body. It shows detailed images of any part of the body, including the bones, muscles, fat, organs and blood vessels.
General Instructions
- Please inform us if you are allergic to contrast media X-ray dye.
- If you are pregnant or think you may be, please inform the Technologist.
- If you wear clothes without zippers and metal this could prevent you from having to change into a hospital gown.
- If the examination will be performed using contrast media X-ray dye, you may be asked to go for bloodwork, eGFR (a lab test that measures your kidneys’ ability to filter toxins or waste from your blood).
How the test is performed
You lie down on a table, which then goes into the doughnut-shaped machine where an X-ray tube rotates around you taking pictures from different angles. You’ll need to hold still during the test to avoid blurring the images.
How to prepare for the test

- Upon arrival, patients will be required to drink several cups of oral contrast for approximately 60 minutes prior to the CT exam.
