Abstract:
Objective To quantitatively analyze the ADC values of different types of benign prostatic hyperplasia(BPH) comparatively with ADC values of prostatic carcinoma(Pca).Methods Seventeen cases of BPH(mean age 69.1 years?4.3 years,ranged from 62 to 77 years) underwent transurethral resection of prostate(TURP) were scanned with the sequence of DWI.DWI(b-values = 0 s/mm2and 800 s/mm2) was performed at 1.5-T system.The hyperplasia tissues resected from central gland were divided into two types pathologically: glandular BPH and stromal BPH.According to the pathological results,ROIs were placed on central gland and the ADC values of two types of BPH were measured.In addition,fifteen patients with biopsy-proved Pca were evaluated and the ADC values of Pca regions were measured.Results The mean ADC values of glandular BPH,stromal BPH and Pca were(1.80?0.20)?10-3 mm2/s,(1.56?0.18)?10-3 mm2/s and(1.27?0.21)?10-3 mm2/s,respectively.Statistically significant difference(F=47.366,P
