title: Magnetic resonance imaging: the basic physical and clinical concepts. Part III.
abstract: Noninvasive evaluation of the human body has become an essential tool in the diagnosis of disease processes. Recent developments in nuclear magnetic resonance imaging (MRI) have extended a powerful chemical analytic technique to the medical imaging field. This article presents the fundamental principles of MRI in terms of the concept of transmission and reception of energy. A selected bibliography directs the reader to a more detailed discussion of the pertinent physics.
