Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging (MRI) is a test that provides pictures of structures inside the body. It produces these images using a magnetic field and pulses of radio wave energy. When the area being studied is surrounded by the magnet, water molecules move in the body. A computer picks up the movements and converts them into pictures. An MRI does not use X-rays to create images. Sentara offers several types of MRIs to meet the exact needs of the patient and referring physician.
