The exam is painless and on average takes between 30 to 45 minutes, excluding preparation time. The amount of time varies depending on the type and number of exams for which you are scheduled.
During the exam, you will be asked to lie on a movable table. A coil or small antenna-like device may be placed over the body part to be examined. Once you have been positioned the technologist will move the table into the MRI scanner which is a long tubular shaped machine.
During the MRI scan, the magnet produces repetitive thumping and tapping sounds. You will be given earplugs to help block the noise of the scanner. You may have the option of listening to music of your choice.
The technologist monitors you throughout the procedure. A microphone system enables you to communicate with the technologist at all times. You will also be given a device that will allow you to alert the technologist if you are having any difficulty during the procedure.
