摘　　要：目的分析PI-RADS v2.1与v2对前列腺癌的评分变化。材料与方法回顾性分析2012年11月至2017年7月行前列腺多参数磁共振成像患者资料53例。以前列腺逐层切片病理为金标准,入组癌灶数量89例。由两名影像科医师按照PI-RADS v2.1和v2标准进行分别评分。结果总体上PI-RADS评分发生变化的癌灶11.2%,移行带占比20.5%、外周带占比4%。PI-RADS≥3病灶比例分别为73.0%、70.8%,差异无统计学意义(P>0.05)。PI-RADS v2.1与v2对所有、移行带及外周带临床显著癌的ROC曲线下面积分别为0.873、0.867、0.841与0.895、0.878、0.884,且差异均无统计学意义(Z=1.098,P=0.272;Z=0.301,P=0.763;Z=1.231,P=0.218)。结论PI-RADS v2.1与v2最终评分变化主要发生在移行带。PI-RADS≥3分的病例数量无明显变化,对临床决策影响不大。Objective:To analyze changes in prostate cancer scores between PI-RADS v2.1 and v2.Materials and Methods:Retrospective review of 53 consecutive multiparametric MRI from Dec 2012 to Jul 2017.Eighty-nine cancers diagnosed by whole-mount step-section pathology were collected and corresponding MRI images were interpreted by two radiologists together using both PI-RADS v2.1 and v2.Results:Comparing v2.1 with v2,11.2%of PI-RADS scores changed(20.5%in the transition zone,4%in the peripheral zone).There was no statistically significant difference in the proportion of PI-RADS≥3 between the PI-RADS v2.1 and v2(73.0%vs.70.8%,P>0.05).There were no statistically significant difference in area under the ROC curve(AUC)between the PI-RADS v2.1 and v2 for detecting all csPCa,csPCa in the transition zone and peripheral zone(0.873 vs.0.895,Z=1.098,P=0.272;0.867 vs.0.878,Z=0.301,P=0.763;0.841 vs.0.884,Z=1.231,P=0.218).Conclusions:The most prominent change between v2.1 and v2 was observed in the transition zone with downgrading from PI-RADS 2 to 1.Overall,the total number of PI-RADS≥3 was not changed significantly,with an expected low influence in clinical management.
