Preparation for the scan
For some examinations, no preparation is required, However if the patient is having a scan of the abdomen, for example, they will be asked not to eat for up to 6 hours before the test.
The scan
Having a CT scan involves lying on a table that slides through the aperture of the scanner. The table is positioned so the part of the body being examined lies within the aperture. The table moves through the gantry as the x-ray source and the detectors rotate around inside.

The Imaging technologist operates the scanner from behind a window, and is able to see, hear and speak to the person being scanned throughout the procedure. The patient will be asked to keep very still and hold their breath for a few seconds.
For some examinations, an intravenous injection of contrast agent is needed to enhance visualisation of organs and blood vessels.
The actual scanning itself takes between a few seconds and a few minutes depending upon the examination, so most of the procedure time is in preparation and confirmation that the images are of sufficient quality. The total length of a CT scan procedure can vary from between 10 to 20 minutes.
