Progress in n.m.r. zeugmatography imaging.
Philos Trans R Soc Lond B Biol Sci. 1980;289(1037):483.
Applications of nuclear magnetic resonance (n.m.r.) zeugmatographic imaging to medical diagnosis and to medical, physiological, and biological research require the development of appropriate imaging instrumentation and ancillary techniques, as well as an understanding of the biological significance of the imaging results. A whole body imaging system, relying primarily upon reconstruction from projections, is under development in the expectation that the reconstruction approach will be the most practical one for many purposes. In addition, injectable magnetic reagents that can selectively change tissue water relaxation times and image contrast are under development so as to increase the specificity and versatility of the measurements. If very high magnetic fields are employed, 31P n.m.r. zeugmatography may be practical at very low resolution for human diagnostic studies and for experiments on perfused organs and small animals. Preliminary images, showing the spatial distributions of different phosphorus metabolites in the compartments of test objects, have been obtained at 146 MHz by reconstruction techniques.
