CT scans are relatively quick, painless and generally safe.
The scanner is like a large ring or doughnut. It is not enclosed, like some other scanners.
A CT scan takes a series of pictures of your body. It uses X-rays but gives a more detailed picture than having a plain X-ray.
The pictures show cross sections, or slices, of your body. They are put together by a computer and scan be viewed on the screen.
This helps us to find the cause of your problem and the best treatment options for you.
X-rays generally use a very low level of radiation. How much depends on how much of your body is scanned. The benefits of the scan are thought to outweigh any risks.
CT scans at our hospitals are by appointment only.
You can read more about CT scans on the NHS website.
Giving your permission (consent)
Before your scan, you will fill in a safety questionnaire that will also ask you if you consent to having the scan. At the time of your scan, the radiographer will confirm your answers with you
This is called verbal consent and might only involve the radiographer checking you are booked for the correct scan.
If you do not want to have the scan, or you are unsure, please tell a member of the team, who will find the most appropriate person to talk to you.
It is your decision and you can change your mind at any time. However, not having the scan might delay your diagnosis.
You can read our consent policy for more information.

Research and clinical trials
Research is vital to improving the care that you receive when you're unwell. You can help improve healthcare by taking part in research studies at our Trust. During your appointment, ask your healthcare professional about research. They'll be happy to tell you about research studies you could be eligible to join.
