What is a 3T MRI scanner?
A 3T MRI scanner is a large cylinder that is open at both ends. You will lie on a motorised table that is moved inside the scanner.Â
You will enter the 3T either head first or feet first, depending on the area of your body being scanned. The radiographer will use a computer to operate the 3T MRI scanner, which is placed in a different room, to keep away from the magnetic field.
You will be able to communicate with your radiographer, usually through an intercom, and they can view you at all times using a television screen.
To ensure the images are not blurred, it is crucial for your body to be still throughout the whole of the scan until the radiologist tells you to relax.
One scan can take from a couple of seconds to three or four minutes. The radiographer may ask you to hold your breath for a few seconds during short scans.
The MRI scanner will make loud tapping noises at specific times throughout the procedure. This is the electric current in the scanner coils being switched on and off.Â
You may be given earplugs or headphones to wear to help. Once the scan is over, your radiographer will move you out of the scanner.
