Frequently Asked Questions
A CT scan is carried out by using a special X-ray machine, which produces an image of a cross-section, or
slice, of the body. The CT scanner consists of a ‘doughnut-shaped’ structure, or gantry, about two
feet thick with a hole in its centre, through which you pass while lying on a couch.
CT scanning involves the use of X-rays. CT scans consist of a special type of X-ray and referring doctors
are very careful to consider whether the benefits of the scan outweigh the risks. If you think you might be
pregnant or breastfeeding, please tell the radiographer prior to your scan as the use of X-rays may be harmful
to your baby.
Many CT examinations involve you having a special dye or contrast agent injected into a vein to increase the
quality of information obtained from the scan. The radiographer will explain any risks associated with this
contrast to you and answer any questions you may have.
You may be given instructions which will relate to the part of the body to be scanned, for example, for some
abdominal scans patients are asked not to eat anything for a few hours before the scan. It is very important
that you follow this preparation.
You will be taken into the CT room and made comfortable lying on the CT couch. Straps and pillows may be
used to help maintain the correct position and keep you still during the examination. The couch will be moved
slowly to position the part of your body under investigation within the ‘doughnut’.
The radiographers will go into the control room but you will be able to talk to them via an intercom, and
they will be watching you and listening all the time.
You will only hear slight buzzing, clicking and whirring sounds.
During the scan, you may be asked to hold your breath or not swallow. However, if you feel any discomfort or
apprehension, please tell the radiographer immediately.
Usually the actual scan takes no longer than 15 to 20 minutes. You may be required to stay in the department
longer either before the examination to drink contrast, or after for 15 to 30 minutes to ensure that you are
No the scan is not painful.
The consultant radiologist will read your CT scan. Your doctor will receive the results with one week of
