Abstract
The recent emergence of in vivo Magnetic Resonance Imaging (Partain et al., 1983) and Spectroscopy (Bottomley, 1989) as clinical and research diagnostic tools has made available new types of information on the local composition of the human body. Since these methods detect signals from the weak nuclear magnetism of materials, they are limited to observing elements which have both strong nuclear magnetic moments and relatively high abundances in the tissue under study. The common proton, which has one of the strongest of nuclear magnetic moments, is very easy to detect by in vivo magnetic resonance. It is also very significant that the times for re-magnetization (T1) and coherent dephasing (T2) depend on the microscopic molecular environments of the protons. These properties have led to the development of proton Magnetic Resonance Imaging techniques capable of providing detailed three-dimensional views of the soft tissue regions of the body, where conventional X-ray tomography has limited use because of poor image contrast.
