CT Scan 

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. You may be required to have an IV inserted prior to the scan for an injection of CT contrast.  

How to prepare for the test 

CT of the Abdomen, Pelvis, Abdo-Pelvic: 

  • Nothing to eat 4 hours prior to the scan, but you can drink clear fluids and take your meds.
  • Upon arrival, patients may be required to drink several cups of oral contrast for approximately 60 minutes prior to the CT exam.

All other CT Examinations:  

  • No special preparation is required.

How the test will feel

CT scans are painless.

“I had surgery at KDH for a knee injury. The experience I had was like no other. The video of what to expect was superbly done and put me at ease before I arrived. The greeter was welcoming and had a great sense of humour. I could tell he really enjoyed his job! The nurse who took care of me explained everything that would happen. I shared with her my fear of IVs and she used a small needle and distracted me so I felt only a pinch. Dr. Marshall explained the procedure and what would happen. He wheeled me into surgery and the people in the OR all introduced themselves and told me what they do. After the surgery, another nurse was there when I opened my eyes and she could see I was confused so she told me it was ok to go back to sleep for a little while. Later, she made sure I was ready to go. I work in the Human Resources field, and I would love to know more about how you create a culture where everyone wants to be at work and be their best selves!”
