A CT or CAT scan or Computerised (Axial) Tomography is a test that combines a series of X-ray images that is taken from different angles around your body. The sophisticated computer within the CT scanner then creates cross-sectional images (slices)and then is able to stack these images together to create a 3-Dimensional image of the body part that has been studied for diagnostic and therapeutic purposes.

It is an excellent medical tool that is used to detect a whole range of disorders and can be used to scan most parts of the body and can evaluate soft tissue and bone including lungs, the heart, coronary arteries, major body organs and the bowel. In particular, it may be used to diagnose subtle fractures, tumours, tiny kidney stones, strokes and blockages of arteries.

Information for Female Patients:

If you are pregnant, or it is possible that you may be pregnant, then a CT scan is usually not performed unless it is an absolute medical necessity to do so. It is possible that an ultrasound or MRI scan may provide similar information and therefore be used as a substitute. Please inform our clinic if this situation applies to you.

  • You will be asked to lie on a movable scanning table.
  • Some examinations may require an IV injection of an iodine contrast media; in this case a drip will be inserted into a vein, usually in the arm.
  • You will be able to communicate with the radiographer throughout the scan.

This may take a few hours, even up to 24 hours for complex scans. Once it is completed, a report will be sent to your referring doctor.
