Magnetic resonance imaging (MRI) is a technology that uses radio waves and a powerful magnet linked to a computer to create detailed pictures of internal organs, blood vessels, muscles, joints, tumors, areas of infection, and more. These very high quality pictures can show the difference between normal and diseased soft tissues of the body, making it especially useful for a wide range of different types of imaging, including neurological and musculoskeletal. If necessary, a contrast agent may be used to help your doctor to see the MRI image more clearly.
The MRI machine can also be used to produce 3-D images that may be viewed from many different angles.
