Knowing more about the testing process - how it works and what should be done beforehand - helps reduce anxiety and makes you a better informed patient. We suggest you take a few moments to read about this extraordinary diagnostic tool.

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 MRI 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 this radio frequency transmitted by your body that is computer-processed and turned into incredibly detailed images.
