The number of pictures taken will depend upon what part of your body is being scanned. The whole procedure of taking multiple scans will require anywhere from 15 minutes to an hour depending upon the information the doctor has requested. The bed you are lying on slides or moves along a track and takes you into the center of the magnet. This is the part some people don't like if they suffer from claustrophobia, the fear of small enclosed places. If you are one of these people, you might find this situation uncomfortable, but if you relax, close your eyes, and listen to the music I think you will find it isn't so bad.
Many people actually fall asleep during the scan and nap through the whole procedure.
So now we're ready to begin. There is a control room nearby where the technician doing your scan is able to see what the camera sees. It is his or her responsibility to get the best possible images for your doctor. The better the image, the better the diagnosis, the better the treatment. The technician surveys the monitors and makes sure he is getting the images your doctor wants and needs to see.
