Magnetic resonance imaging is a type of scans which uses strong magnetic fields and radio waves to produce images of inside of the body. The scan can last up to an hour and it is very important to keep as still as possible during the scan. During the scan you will be lying on a flatbed that is moved into a doughnut shaped scanner. You will be lying in a large cylinder-shaped magnet during the time when the scan is performed. When you are inside the scanner you will be able to talk to the radiographer through an intercom and they will be able to see you on a television monitor throughout the scan. During the scan the scanner will make loud tapping noises and is because of the electric current in the scanner coils being turned on and off. You can use earplugs or headphones during the scan.
Though MRI scan is safe and painless it can cause claustrophobia. However, most of the patients can manage with support from radiographers. As there is a very strong magnetic field around the patient any electronic devices or metal implants in the body should be informed to the radiographer beforehand.
