摘　　要：目的:探讨前列腺影像报告和数据系统(PI-RADS)1.0中MRI动态增强(DCE-MRI)时间信号-强度曲线类型与2.0中DCE-MRI阴阳性判断对前列腺癌的诊断价值。方法:对53例经病理证实的前列腺癌患者的DCE-MRI结果进行分析,分别比较两种方法对中央腺体、周围腺体的癌灶区及非癌灶区的诊断价值。结果:对于中央腺体的非癌灶区、周围腺体的癌灶区及非癌灶区的诊断,2.0中DCE-MRI阴阳性的判断明显优于1.0中DCE-MRI时间信号-强度曲线类型,且有统计学意义(P<0.05)。结论:对于前列腺癌的诊断,PI-RADS 2.0中DCE-MRI的阴阳性判断明显优于1.0中DCE-MRI的时间信号-强度曲线类型的判断,具有更好地临床应用价值。Purpose: To compare the diagnosis value of prostatic cancer between DCE-MRI TIC in Prostate imaging reporting and data system v1(PIRADS-1) and enhancement character of DCE-MRI in Prostate imaging reporting and data system v2(PIRADS-2). Methods: DCE-MRI data of 53 cases of pathologically proved prostate cancer were retrospectively analyzed. The diagnosis value of prostatic diseases cancer between DCE-MRI TIC in PIRADS-1 and enhancement character of DCE-MRI in PIRADS-2 were compared in central zone and peripheral zone. Results: The enhancement character of DCE-MRI is better than DCE-MRI TIC in the diagnosis of prostatie cancer in peripheral zone(P<0.05). Conclusion: The enhancement character of DCE-MRI is better than DCE-MRI TIC in the diagnosis of prostatie cancer. It is useful for the diagnosis of prostatie cancer.
