Single-voxel spectroscopy and 2D spectroscopic imaging of the prostate at 3 T was performed using standard surface coil. Spectra of 53 healthy volunteers were processed using customized LCModel. It was found that metabolite-to-citrate spectral intensity ratios were significantly lower in older individuals than in younger. Our results demonstrate that the prostate spectroscopy at 3 T is feasible using surface coil. LCModel provides a high level of accuracy for analysis of prostate spectra. Our results indicate that each 1H MRS study of the human prostate should include age-matched controls.
