摘要

目的:评估不同年资放射诊断医师使用前列腺影像报告和数据系统2.1版(PI-RADS v2.1)测试多参数磁共振(mpMRI)诊断前列腺临床显著癌(csPCa)的病变部位及评分的一致性.方法:回顾性评估2018年1月1日～2021年2月28日期间因前列腺疾病接受mpMRI扫描的具有完整明确病理结果的583名男患者的MR图像,3位不同年资放射诊断医师(前列腺 MRI诊断A=8年,B=6年,C=3年)根据PI-RADSv2.1分别对纳入病例图像进行独立诊断分析,利用Kappa及Fleiss'Kappa检验评估3位医师的诊断病变部位及评分的一致性.结果:三者诊断病变部位的一致性均表现出中等,中高年资医师的一致性高于中低及高低年资医师的一致性,两两相互比较Kappa=0.63(A vs.B)中等、0.51(B vs.C)中等、0.45(A vs.C)中等,三者整体比较(Kappa=0.52中等);三者诊断评分的一致性:两两相互比较Kappa=0.70(A vs.B)中等、0.76(B vs.C)较好、0.64(A vs.C)中等,三者整体比较(Kappa=0.43中等),同时诊断csPCa部位及评分两两相互比较以及三者整体比较的一致性均具有统计学意义(P=0.000).结论:不同年资医师利用PI-RADS v2.1评估mpMRI诊断csPCa的部位及评分的一致性均为中等,病变部位诊断一致性方面中高年资医师较低年资医师更好;提高病变部位及评分的诊断一致性仍需加强PI-RADS v2.1的专业培训.

Abstract

Objective:To evaluate the consistency of radiologists with different years of experi-ence in the diagnosis of clinically significant prostate cancer(csPCa)using multi-parametric magnetic resonance imaging(mpMRI)based on the Prostate Imaging Reporting and Data System version 2.1(PI-RADSv2.1).Methods:A total of 583 patients who underwent prostate mpMRI scans with patho-logical results from January 2018 to February 2021 were retrospectively reviewed.All images were in-dependently analyzed by three radiologists with different levels of experience in prostate MRI:(A=8 years,B=6 years,C=3 years)according to PI-RADSv2.1.Kappa and Fleiss'Kappa tests were used to evaluate the consistency of the three radiologists'diagnoses of lesion location and score.Results:The consistency of the lesion location diagnosis among the three radiologists was moderate,with the con-sistency of the middle and high experience radiologists being higher than that of the low and high ex-perience radiologists.The Kappa values of pairwise comparison were moderate,0.63(A vs.B),0.51(B vs.C)and 0.45(A vs.C)respectively,and 0.52(overall comparison).The consistency of score diagno-sis among the three radiologists was moderate,with the Kappa values of pairwise comparisons being 0.70(A vs.B,moderate),0.76(B vs.C,good),and 0.64(A vs.C,moderate),whereas a lowest Kappa value of 0.43 for the overall comparison.The consistency of the diagnosis of lesion location and score of csPCa was statistically significant(P=0.000).Conclusion:The consistency of different levels of expe-rience radiologists in evaluating the location and score of csPCa using PI-RADS v2.1 is moderate.To improve the diagnostic consistency of lesion location and score,professional training in PI-RADS v2.1 still needs to be strengthened.
