Age dependence of citrate concentration and its ratio to creatine and cholines in the prostate was studied in healthy volunteers at 1.5T and 3T MR systems using 3D CSI sequence. Coefficient of asymmetry between left and right peripheral zones was calculated. Significant increase in the citrate concentration was found between 20 and 70 years and equation parameters for age dependence of prostate metabolites were determined.
