MRI (magnetic resonance imaging), involves using a combination of radio waves and a powerful magnet to create detailed images of the inside of your body. MRI scans are painless do not involve any type of harmful radiation.
As the scanner operates using a very powerful magnet, you will be asked to remove any metal before entering the scan. This can include jewellery, watches, dentures, underwire bras and hair pins. Your radiographer will then go through the details of the scan with you and answer any questions you may have.
To produce the clearest possible images, you will be asked to lie very still during the scan. You will be given headphones to wear, from which you’ll be able to communicate with the radiographer. The procedure itself is painless, however some patients may suffer from anxiety or claustrophobia, making it appear quite daunting. The radiographers are able to provide you with some helpful tips and advice or a mild sedative. In some cases, patients may be given a dye injected through a vein in the arm to help enhance the appearance of certain details.
MRI scans are typically an outpatient service and you’ll be able to continue with your day as normal once the procedure is complete.
MRI scans can be used to examine:
- Head and neck
- Small Bowel
