摘　　要：目的:探讨外周带前列腺癌鉴别诊断中磁共振灌注加权成像(PWI)定量参数的价值。方法:回顾性分析2014年1月至2015年10月在濮阳市安阳地区医院行前列腺磁共振(MRI)扫描的前列腺疾病患者50例,分析PWI定量参数在前列腺癌及良性鉴别上的价值。结果:前列腺癌组、良性病变组转运常数(K^(tras))、血液回流常数(K_(ep))比较,差异具有统计学意义(P<0.05);血管外细胞外间隙体积百分数(Ve)比较,差异无统计学意义(P>0.05)。结论:在前列腺外周带前列腺癌鉴别诊断中,PWI定量参数K^(tras)、K_(ep)具有重要的诊断价值,可作为鉴别的重要参数指标。Objective To evaluate the value of magnetic resonance perfusion weighted imaging（PWI） quantitative parameters in the differential diagnosis of prostate cancer. Methods We retrospectively analyzed 50 cases of prostate cancer patients with prostate cancer in the hospital of Anyang, Puyang City, and analyzed the value of PWI quantitative parameters in prostate cancer and benign identification. Results The difference of K^tras and Kep between prostate cancer group and benign lesion group was statistically significant（P〈0.05）. Ve, the difference was not statistically significant（P〈0.05）. Conclusion In the differential diagnosis of prostate cancer in the prostate, the quantitative parameters of PWI K^tras and Kep have important diagnostic value and can be used as an important parameter index.
