Magnetic resonance imaging (MRI) uses a powerful magnetic field, radio waves, and a computer to produce detailed pictures of the body’s internal structures. These pictures are clearer, more detailed, and more likely in some instances to identify and accurately characterize disease than other imaging methods.
MRI is used to evaluate the body for a variety of conditions, including tumors and diseases of the liver, heart, and bowel. It may also be used to monitor an unborn child in the womb. MRI is non-invasive and does not use ionizing radiation.
