Nuclear magnetic resonance imaging

Preview

One of the most exciting developments in medicine within the past decade has been the application of nuclear magnetic resonance (NMR) imaging to clinical diagnosis. Although medical use of NMR imaging is still in its infancy, this revolutionary procedure already competes favorably with computed tomography and ultrasound. It not only produces high-resolution three-dimensional images of the body safely and noninvasively but also has the potential to allow evaluation of tissue pathology and metabolic function. Dr Vannier, who is a pioneer in application of this space-age technology to medicine, explains the important advantages of NMR imaging, describes its spectacular achievements to date, and counsels physicians on its clinical applications.
