探讨磁共振多b值扩散加权成像在前列腺病变中的应用价值
The diagnostic value of multiple b-value diffusion weighted imaging in prostate disease
摘要
Abstract
Objective: To retrospectively evaluate the diagnostic value of multiple b-value diffusion weighted imaging in prostate disease of MRI. Materials and Methods: Ten healthy volunteers, 36 cases of prostatic hyperplasia (BPH) and 24 cases of prostate cancer (PCa) which pathologically confirmed were included in this study. ADC values were measured at b-value of 200, 400, 600, 800 and 1000 s/mm2 respectively. The quantitative comparison was applied between these groups. Results: With the increase of b value, the ADC value of PCa decreased gradually. However, in BPH patients, the ADC values did not show a significant change. The difference of the b-values of prostate cancer, prostatic hyperplasia and normal prostate tissue had statistical difference between groups. Conclusions: The ADC values of different b-values measured by DWI could help to differentiate between prostatic hyperplasia, prostate cancer and normal prostate.关键词
