The MRI scanner will make loud tapping noises at certain times during the procedure. This is the electric current in the scanner coils being turned on and off.
The scan can take between 10 minutes to over an hour to complete. This depends on the part of the body being imaged and what type of MRI is required to show the information. Before the scan begins, the radiographer will tell you how long the scan takes, so you know what to expect.here are no after effects of the MRI itself. You will be able to carry on your day as planned once the test has been completed. If you require sedation for the scan, the MRI facility will give clear instructions on what to do before and after the scan.
