Magnetic resonance imaging (MRI), nuclear magnetic resonance imaging (NMRI), or magnetic resonance tomography (MRT) is amedical imaging technique used in radiology to visualize internal structures of the body in detail. MRI makes use of the property of nuclear magnetic resonance(NMR) to image nuclei of atoms inside the body. MRI can create more detailed images of the human body than are possible with X-rays.
