Computed tomography (CT) uses X-rays to create cross sectional images of your body. The X-ray beam is rotated around the body, captured on detectors and processed by a computer to give images in ‘slices’. This information can be viewed at many angles and in different ways, including 3-dimensional rendered images.
Patients referred to Taranaki Radiology for a CT examination will have their scan performed on the either:
- our CT scanner at our premises at Fulford Street or
- Taranaki Base Hospital on one of our dedicated sessions.
Some CT examinations require preparation prior to your appointment which will be discussed with you at the time of making your appointment. The preparation for the scan varies depending on the area of the body to be scanned. For example, Abdominal CT scans may require you to fast from food and fluids for a period of time and then drink a special drink over the hour before your scan. This is to show the intestines clearly on the scan. If you are having an examination requiring IV contrast media then we will also require a recent blood test result to check your kidney function.
