16 cases of benign disease of prostatic peripheral zone all proved pathologically or clinically, MR imaging and 3D 1H MRSI were performed in each case. Most of benign lesion were nodular and well-defined lesion.Prostate cancer presented mainly as patch-like lesion with nodular feeling and ill-defined.The average ratio (0.680.17) of choline+creatine/citrate (Cho+Cre/Cit ) of benign lesion were significantly less than that of prostate cancer.Combined the results of MR imaging and 3D 1H MRSI will play a important role in diagnosing benign lesion of prostatic PZ.
