Magnetic resonance imaging (MRI) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in your body. It is a safe method used that employs a magnet and radio waves, and does not require additional x-rays or invasive procedures. There is no risk of exposure to radiation during an MRI procedure, because radiation is not used.
An MRI helps a doctor diagnose a disease or injury, and it can monitor how well you’re doing with a treatment. MRI's can be done on different parts of your body. It's especially useful for looking at soft tissues and the nervous system.
