Abstract: 目的探讨MR弥散加权成像(DWI)表观弥散系数(ADCs)在前列腺病变诊断中的价值.方法对良性前列腺增生(BPH)42例、前列腺癌(PCa)15例进行MR弥散加权成像,测算病灶表观弥散系数(ADCs).结果 BPH组前列腺中央带增生结节与外周带的平均ADC值分别为:(1.783±0.282)×10-3mm2/ s和(2.025±0.358)×10-3mm2/ s;前列腺癌组前列腺中央带与外周带癌灶平均ADC值分别为:(1.632±0.082)×10-3mm2/ s和(0.267±0.07)×10-3mm2/ s (P<0.05).结论 DWI对于BPH、PCa可提供定量诊断信息,反映其病理变化;ADC值是鉴别BPH与PCa的一个很有价值的参数.
