Understanding MRI Magnetic resonance imaging (MRI) is one of technology's most advanced diagnostic tools for today's physician. It allows your physician to see inside your body without surgery or the use of ionizing radiation. MRI uses a powerful magnet, low-intensity radio waves and computer technology to create detailed images of the soft tissues, muscles, nerves and bones in your body.
How Scanners Work
The main component of the MRI system, or scanner, is a magnet. This magnet causes your body's hydrogen atoms to align themselves in such a way as to receive radio signals from the magnetic resonance system when your body receives these signals, it reacts by sending its own radio signals back to the machine. It is the radio frequency transmitted by your body that is computer-processed and turned into incredibly detailed images.
