The phosphorus metabolites present in the prostate and surrounding tissues of a healthy volunteer were studied by 31P magnetic resonance spectroscopic imaging at 7 Tesla with an endorectal transceiver coil. The spectral resolution was high enough to distinguish the various compounds in the phoshpomonoester (PME) and phosphodiester (PDE) region. Separate resonances in the range of inorganic phosphate probably originate from compartments with different pH, but may arise from other compounds as well.
