When you have a CT scan in the children's hospital, the radiographer first measures your weight and height, you then go into the scan room. The CT scanner is really quick and not noisy. You only have to lie still as a statue for a few minutes and then the scan is complete.
Please note this recent change in the guidance in Scotland (2023):
Parents can only accompany their child if absolutely required to gain compliance and achieve a diagnostic scan. The Radiographer risk assesses each patient to see if the child can manage without having their parent in the room. In some cases the parent is in the room for position and describing the scan, right up until the part where the scan is acquired where they step outside the room.
Each patient is different.
