CT Scan
A guide for patients and carers
Will I need an injection?
When certain areas of the body are scanned, you may need an injection of a special dye known as a contrast agent which helps to see more detail on the pictures. If you need an injection it will be given into a vein in your arm by a radiologist or one of the radiographers trained to give injections. The injection may give you a general warm feeling, but this goes away quickly. People affected by asthma should inform the staff before their appointment as they may need 48 hour steroid cover.
