magnetic resonance imaging mag*net"ic res"on*ance im"ag*ing n. (Medicine) a medical diagnostic procedure utilizing the phenomenon of {nuclear magnetic resonance} to generate images of internal parts of the body. It depends on the differential absorption of electromagnetic radiation by different types of living tissue in a magnetic field. It is complementary to X-ray imaging in that the softer tissue show more prominently in magnetic resonance images, rather than bone, as with X-rays. It is a non-invasive procedure, allowing such images to be obtained without penetration of the tissue by objects. It is abbreviated {MRI}. As with {computerized tomography}, the results are usually presented as images of sequential planar sections of that part of the body of concern to the physician. [PJC]
