Conference paper


P31 MR spectroscopy (MRS) is a new noninvasive means which provides in vivo information about relative concentrations of myocardial high-energy phosphates and phospholipids in man. Phosphorus spectra of normal myocardium show different peaks for phosphocreatine (PCr), adenosine triphosphate (ATP), as well as for phosphodiesters (PDE) and phosphomonoesters (PME). Some of the resonances are contaminated by such compounds as NADP, NADPH or adenosin-diphosphate, but these contributions usually account for less than 10% of the resonances. A typical example of a phosphorus spectrum for sceletal muscle is given in Fig. 1. As the various resonance peaks overlap, a mathematical curve fit has to be performed and is given as a dashed line in Fig. 1.
