Magnetic resonance imaging: a noninvasive diagnostic procedure employing an MR scanner to obtain detailed sectional images of the internal structure of the body.
MRI (magnetic resonance imaging) assists physicians in detecting and defining the differences between healthy, diseased or injured tissue. This technology uses magnetic fields, radio waves and complex computer processing to produce exceptionally clear images of organs, soft tissues, bone and other internal body structures for diagnostic purposes. Functional MRI was developed in 1992.
MRI exams are painless and can be completed with no exposure to radiation. Most MRI exams can be completed in an hour or less
