Abstract

Since Nuclear Magnetic Resonance was first used to image the human body in the late 1970's (1), image quality has steadily improved. At this time, image quality from magnetic resonance (MR) imaging, as it is now called, rivals that produced by x-ray computed tomography (CT). The cross-sectional tomographic images of the body produced by magnetic resonance display hydrogen density in the body, modified by the magnetic relaxation times, Tl and T2 (2). In addition to imaging the body, MR can also provide spectroscopic information from a specified region of interest within the body. Spectroscopy gives the concentration of different chemical species of the same chemical nucleus (e.g., P-31, C-13, Na-23), again modified by the magnetic relaxation times. Although such spectra have been obtained from the human body, the role of spectroscopy in clinical medicine has yet to be defined. The following discusses the indications for magnetic resonance imaging in current medical practice relative to existing imaging modalities such as CT. Potential future indications for magnetic resonance (including both imaging and spectroscopic applications) will be discussed.
