What are the risks and side effects?
MRI scans do not use X-rays and have no known risks or side effects. In some cases, individuals may experience sensations of claustrophobia or discomfort. In extremely rare instances, an allergic reaction to the contrast agent may occur.
Heating and thermal burns
Burns can occur during an MRI scan, but you may not feel them immediately. This is because the heating affects the fatty tissue below the skin, where there are no pain sensors. As a result, the burn may not become noticeable until it reaches the skin surface, which can take up to 24 hours after the scan.A burn may develop as red or peeling skin , swelling, white or charred skin or blistering.
If this occurs, please contact your GP if further assistance is required. In all cases, please contact the CDC to inform us that a burn has occurred. It is important that we are aware of any injury, that has been caused by an MRI examination so that we can give further guidance.
Pregnancy and breast feeding
If you think you may be pregnant, please contact the CDC immediately on 01865 226644.
If you are feeding your child breastmilk, then you do not need to stop this as extremely little of the contrast gets into the breast milk.
What Happens in the MRI Unit?
Upon arrival, a staff member will review your MRI safety sheet with you. You will need to remove all metal objects, including all jewellery and glasses which can be stored safely in a locker. You may need to change into a hospital gown.
What happens during the Scan?
During the scan, you will lie on a table that slides into the MRI scanner, which is open at both ends. It is important to stay still for clear images. The radiographer will be in contact with you and can see you throughout the scan. You will have a buzzer to alert the radiographer if needed.
Scans take 15 to 30 minutes, and the radiographer will inform you of the estimated duration. You may receive an injection to help with the diagnosis.
