Abstract:
Objective To investigate the metabolic characteristics,clinic values of different tissues in benign prostatic hyperplasia by correlating MR spectroscopy(MRS)with whole pathologic sections.Methods MRS presentation was studied in 16 patients with benign prostatic hyperphsia.The peak values of citrate,choline and creatine were measured,and the mtios of(choline+creatine)/citrate(cc/c)were obtained.After suprapubic transvesical prostatectomy,the specimens of whole pathologic sections were observed.The values of cc/c of different pathologic types were compared statistically with One.way-ANOVA and t test. Results MRS results were obtained in 578 units,which included 233 glandular tissue units.130 matrical tissue units.165 mixed tissue units and 50 tissue units around urethra.The ratios of (choline+creatine)/citrate of glandular,matrical.mixed tissues and units around urethra were 0.59±0.29.1.23±0.38.0.80±0.27 and 0.68±0.33(F=3.49.P＜0.05).The t tests were carried out between every two tissues.The t valUes between glandular tissues and matrical.mixed tissues were 19.60 and 7.09.P＜0.05:the t values between matrical tissues and mixed tissues.units around urethra were 13.22 and 9.42,P＜0.05;the t valUes between mixed tissues and units around urethra was 9.42,P＜0.05.Condusions,The ratios of cc/c ofthree prostate tissues were different in MRS.The metabolic characteristic of the units around urethra Was near to glandular units.MRS may be valuable to the distinctive diagnoses of prostate diseases.
