Computed Tomography

CT uses an x-ray machine and advanced computer programs to create 2D and 3D images of your body. CT is an essential imaging modality which utilizes the latest and most advanced medical technology to detect and assist with the diagnosis of many conditions.


Our staff will inform you of any specific preparation required for your CT scan at the time of your booking. 

Certain CT examinations will require preparation:

  • Fasting for 2-4 hours prior to the scan or blood test (4-6 hours for IV contrast injections)

  • Being well-hydrated.


If you are pregnant or think that you may be pregnant, please inform our staff at the time of booking as alternative imaging may need to be arranged.
