Abstract:
Objective To investigate the MRS characteristic of low T_2 signal in peripheral zone of prostatitis and prostatic carcinoma(Pca) and to evaluate the role of MRS in the discrimination of prostatitis and Pca.Methods After biopsy,24 patients with Hypointense T_2 signal in prostatic peripheral zone were divided into two groups:prostatitis and Pca.3D MRS was performed on the low T_2 area of peripheral zone to measure the ratio of(Cho+Cre)/Cit.Results The mean ratio of(Cho+Cre)/Cit in low T_2 area of prostatitis was 0.98?0.17,whereas that of Pca was 1.41?0.31,statistically significant difference was detected(t=8.89,?
