It is very important to keep as still as possible during your MRI scan, as movement will blur the pictures. The scan can last from 10 to 60 minutes, depending on the size of the area being scanned and how many images are taken.
An MRI scan is a painless and safe procedure. MRI scans do not involve exposing the body to X-ray radiation and are considered very safe. However, it may not possible for some patients to have an MRI scan. People who have had pacemakers, aneurysm clips, metal heart valves or metal fragments in their eyes will need to discuss with the radiographer whether a scan is possible. You will be asked to fill out a questionnaire prior to the scan to identify any contraindications that may prevent you from having an MRI scan.
In some cases, an injection of a special contrast dye is given into the bloodstream via a vein in your arm. This helps to give clearer pictures of certain tissues or organs being examined. A radiologist will decide whether this is necessary.
