Having an MRI: Page 7 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 Just like having your picture taken, having an MRI does not hurt. When it is time to start, the technician will probably go behind a glass window to take the pictures. There are microphones inside the machine so you can talk to the technician. It sounds like a humming noise and you'll hear some thumping, like a drum. You may be able to wear ear plugs. Your MRI might be as short as one cartoon show or as long as three cartoon shows depending on the pictures that your doctor needs.
