Into the chemistry of the heart.
Using a new technique called depth-resolved surface coil spectroscopy, Paul A. Bottomley of the General Electric Research and Development Center in Schenectady, N.Y., obtained phosphorus spectra from the heart of a volunteer. These spectra showed the relative amounts of inorganic phosphorus and the metabolites phosphocreatine and adenosine triphosphate -- normally present in minute quantities and very difficult to detect. Changes in the ratios of these substances, which are involved in the transfer of energy in licing cells, often mirror the effects of heart disease. Bottomley's report appears in the Aug. 23 SCIENCE.
