The machine is often described as looking like a “donut” with a bed sliding through a circular hole.
You will be asked to lie down on the CT bed. The bed will move during the scan and you may be asked to follow breathing instructions.
If iodinated contrast is required and injected, most people will get a strange metallic taste in the mouth and feel a warm sensation through the body. This warm sensation can feel like you have wet yourself, even though you have not. Do not feel concerned if this happens, it is a common sensation and usually goes away within a few of minutes.
Once the radiographer has checked the images to ensure the appropriate areas have been shown, they will come into the room to help you off the bed.
It is important to try not to move during the scan as it will affect the quality of the pictures.
