COMPUTED TOMOGRAPY (CT)

What is a CT scan?

A CT scan is a medical imaging procedure that uses digital technology and X-rays to produce cross-sectional images. A CT scanner looks like a large doughnut attached to a flat table that moves through the middle of the donut. The scanner is quiet and the procedure is painless.

This non-invasive test is used for a range of purposes including to:

  • Diagnose diseases and disorders of the stomach and bowel, kidneys, bladder, appendix, liver, spleen and pancreas

  • Identify sources of pain and trauma

  • Diagnose vascular disorders that can lead to stroke, heart attack or kidney failure

  • Aid in planning radiation treatments for tumours

  • Guide biopsies and other minimally invasive procedures

Before the appointment

Most CT scans require no special preparation. Capital Radiology staff will advise you at the time of booking if any preparation is needed for your scan. Be sure to wear comfortable clothing, and note that you may be asked to change into a gown and remove metal objects including glasses, jewellery and dentures as they can affect the scan quality.

A booking is required for most CT scans. The locations of our CT scanners are listed on your Capital Radiology referral form, or you can find your most convenient Capital Radiology site by viewing our locations. We accept all radiology referral forms, so even if you have a form from a different service provider we will happily perform your test.

Please remember to bring:

  • Your referral form

  • Medicare card / concession card

  • Any prior imaging

FAQs

What happens when I arrive?

When you arrive at our clinic you will be greeted by our friendly reception team. We will ask you to complete a questionnaire and sign a consent form. Our radiographer will explain the examination to you and what to expect.

In some cases, a contrast injection into a vein in the arm will be needed to improve the scan’s accuracy. This is generally safe, but we will need to know if you have any allergies, diabetes, renal impairment or thyroid conditions. You might notice a warm sensation or a metallic taste for a short time after the injection.

NOTE: Women should inform the radiographer if there is any possibility of pregnancy.

When will my doctor receive the results?

Our radiologist will interpret your examination and send the results directly to your doctor who, as a general rule, will receive them in 2–3 working days.

Is there a cost?

Most CT scans are covered by Medicare.
