COMPUTED TOMOGRAPHY (CT)

What is a CT examination?

CT uses x-rays with detectors and a powerful computer to produce 2D slice images or 3D images.  CT can show bones, soft tissues and blood vessels well.  CT can also be used to guide interventional procedures or treatment.

We use the newest type of CT technology called 'Multislice CT'. This type of CT covers the body with thinner slices, producing more detailed images in a shorter time. We use the very latest low dose CT equipment at Sandringham Hospital Radiology.

How do I prepare for my CT?

  • If you have been referred for a CT scan by your doctor and would like to make a booking, please contact 9076 1411
  • Please inform your doctor & booking receptionist if you have diabetes, previous allergy to contrast, kidney problems or thyroid gland problems.
  • Please inform the booking clerk if you weigh more than 180 kgs.

Just prior to the CT scan

  • You may be asked to fast immediately before the examination.  Please continue to take your regular medication unless otherwise advised by your doctor.
  • When you arrive, you may be asked to drink special fluids for around one hour before your scan.
  • You may need an Intravenous line inserted to administer x-ray contrast.
  • You will be asked to remove clothing and jewellery from the body area being scanned.

During the CT examination

  • A radiographer will do your scan.  If you require contrast injection, this is done by the radiologist.
  • A CT Scan will usually take 5 to 20 minutes, but this may vary.  The radiographer will advise you.
  • You will be asked to lie very still for the entire examination.  You may be asked to hold you breath for a short time. This stops the images from blurring.

What do I do after the CT scan is finished?

  • Return to your doctor to discuss the examination results.
  • The radiologist’s report and your images are automatically forwarded to your doctor.
  • Eat and drink normally after your CT scan is finished.
  • If you have had an interventional procedure, you will be given an information sheet at discharge with specific information about your procedure.
