Computed Tomography (CT)

CT stands for computed tomography and uses multiple x-ray images to produce fine cross sectional slices through the part of the body being investigated. It’s not that different to taking a slice of bread and looking at that particular slice to see what’s going on in that area. It enables detailed images to be taken of your entire body and the image slices can be reconstructed to produce a 3D image.

Things to know

You will be asked to change into a gown for your scan.

For some CT scans, you may need to be injected with a special solution called contrast. If you are pregnant, please let our staff know.

A CT looks like a doughnut (the technical word for it is a gantry), with a bed passing through the middle. You will be asked to lie on the bed as still as you can as the bed moves through the opening in the gantry. The gantry isn’t a long narrow tunnel – it is actually quite wide and short.

Throughout the CT you will be able to see out both sides of the gantry as well as communicate with your technician.

The bed will move backwards and forwards collecting images during this time. During this time you may be asked to hold your breath for several seconds. Your Radiographer will explain this to you before your scan.

A scan can take between 5 minutes and 30 minutes.
