A CT (computerised tomography) is a painless, non-invasive procedure which uses specialised X-ray equipment to scan for inflammation, disease, cancer or other health conditions. 

The scan is done inside a CT scanner, a large donut-shaped machine, which takes images of the inside of your body. It may be necessary for you to have a dye injection (contrast medium), or drink a liquid to help improve the quality of the scan images. Both dyes are harmless and will pass out through your urine after the procedure. 

What is a CT scan?

A CT scan is great for viewing parts of the body difficult to reach with other procedures. These scans are able to view: 

  • Bones
  • Internal organs
  • Soft tissue
  • Muscles
  • Bloody vessels

They work effectively by sending out multiple beams of X-rays at different angles, giving a clear picture of the scanned area. Depending on the reason for the scan, it will take between 15 minutes and 1 hour. 

What happens after the CT scan?

It is rare to experience any complications from CT scans; however, it is possible to have an allergic reaction to the medium contract injection. In this case, there is medication on hand to deal with the reaction immediately.

Your images and report are reviewed and sent on to your healthcare specialist to give a diagnosis and organise any further treatment, if necessary.
