MRI’s save millions of lives every year by getting us clear images of internal body structures so that we can diagnose and treat patients quickly.
Not all waves are the ones like in the ocean. For example there are radio waves. Radio waves are a type of electromagnetic radiation …show more content…

The MRI machine looks like a long narrow tube with openings at both ends. At the opening of the tube, the patient lies down on a moveable table that slides in and out of the machine. A technologist monitors them from a different room which they can talk to through a microphone.
