DGMC Radiology CT scan services

A CT or CAT scanner is a doughnut-shaped machine that uses advanced x-ray technology to create images of your body.

A computer then reconstructs the cross-sectional images of your body, called slices or sections.

Advancements in CT technology now make it possible to diagnose certain diseases earlier and more accurately than with other imaging tools.

Our radiology practice uses the most advanced scanner technology available, providing images of exceptional quality and the lowest possible radiation dose.

Our new 64 slice scanner allows us to perform advanced 3-D reconstructions.

Patient’s Guide to CT Scan Services

For scans of the abdomen and pelvis, please do not eat solid foods for 6 hours prior to your CT appointment. You may drink clear liquids (black tea/coffee, water or juice) prior to your scan. Please notify the radiographer if you are diabetic.

Please take all regular medication that your doctor has prescribed for you.

Allergic reaction to contrast is extremely rare, even in patients with allergy to other things. We use iodine containing contrast media as a “dye” to light up areas of increased blood supply. If you think you may be allergic to the IV contrast material or iodine, or have experienced a prior reaction to IV contrast material, please notify the x-ray department prior to your appointment as we need to provide you with a prescription for cortisone/steroids to counteract an allergic reaction.

If you have a history of kidney disease or are at risk for kidney disease please notify your referring physician prior to your CT scan appointment. You can have a blood test (urea and creatinine) to determine your kidney function prior to your scan.

We encourage our patients to wear loose, comfortable clothing that does not have any metal buttons or zippers. Otherwise you may be asked to change your clothes and wear a hospital gown. We have private dressing rooms but it is best to leave your valuables at home or with a family member. We may ask you to remove any jewellery, dentures, glasses or any metal objects which may interfere with the CT scan.

  • Please arrive 15 minutes prior to your scheduled appointment time to complete paperwork at our reception desk. We try to keep arranged times but emergencies may delay appointment times.
  • Upon arrival you will be given additional contrast to drink.
  • You will also need to sign a consent form.
  • The scan will take approximately 30-45 minutes.
  • When colon or small bowel needs to be visualized, you would need to drink oral contrast in order to see the loops of small intestine & large bowel loops more distinctly. It creates a white coating and allows the bowel to stand out against the other abdominal structures when loops of bowel are filled with it.
  • CT scan preparation takes much longer than the scan itself. CT scan preparation can take 4-6 hours if oral contrast is required. This is because oral contrast has to travel through the entire length of the intestinal tract after you start drinking it.

You will be required to bring your medical aid card, request form from referring doctor, and authorisation number from your medical aid.
