Magnetic Resonance Imaging (MRI) News and Research

RSS

Magnetic resonance imaging (MRI) uses a large magnet and radio waves to look at organs and structures inside your body. Health care professionals use MRI scans to diagnose a variety of conditions, from torn ligaments to tumors. MRIs are very useful for examining the brain and spinal cord. Also called: Magnetic resonance imaging, NMR, Nuclear magnetic resonance.
