Before you have a CT scan (computerised (axial) tomography scan), you will be asked about any existing conditions, medicines you are taking and if you have any allergies. This is to make sure that there is no risk of reactions.
If you are a woman of childbearing age, you will be asked if you are pregnant. CT scans are not recommended for pregnant women unless there is an urgent medical reason, as there is a small chance that the X-rays could cause harm to an unborn child.
If you are claustrophobic and feel anxious about having a CT scan, tell the radiographer before your appointment. They can give you advice to help you to feel calm and, if necessary, arrange for you to have a sedative.
You will be asked to remove your clothing and put on a gown. You should also remove any jewellery or metal fastenings because metal interferes with the scanning machine. If you are having a head scan, you may also be asked to remove contact lenses, dentures, hair clips and hearing aids.
Depending on what part of your body is being scanned, you may be given a contrast medium. This is a liquid that contains a dye, which improves the image of certain tissues or blood vessels. A contrast medium is usually harmless (see Risks of CT scan) and will pass out in your urine after the scan.
A contrast medium may be swallowed as a drink, given as an enema in your back passage or injected into the blood stream, depending on the part of your body that is to be scanned.
Many CT scans require an injection of contrast medium into a vein in the hand or arm. This is to help a radiologist tell the difference between blood vessels and other structures.
Some people find that the contrast medium injection makes them feel warm and as if they want to pass urine. This sensation is normal and usually passes quickly.
