摘要
目的探讨肝细胞肝癌高危患者肝脏占位性病变的超声造影肝脏影像报告和数据系统(contrast-enhanced ultrasound liver imaging reporting and data system,CEUS LI-RADS)与磁共振肝脏影像报告和数据系统(magnetic resonance imaging liver imaging reporting and data system,MRI LI-RADS)分类的一致性。方法回顾性分析2017年8月至2019年8月在浙江大学医学院附属第二医院就诊的173例肝细胞肝癌高危患者肝脏占位性病变(217个病灶)的影像学资料,分别由2名超声造影(CEUS)与磁共振成像(MRI)诊断医师按照CEUS LI-RADS 2017版和MRI LI-RADS 2018版分类标准对病灶进行判读,通过Kappa检验评估观察者间及两种影像学LI-RADS分类的一致性。结果CEUS LI-RADS观察者间一致性与MRI相当(Kappa=0.606、0.603);CEUS LI-RADS与MRI LI-RADS两种影像学总的一致性中等(Kappa=0.564),其中两种影像学对LI-RADS-3、M、4和5类的一致性分析,其Kappa值分别为0.739、0.551、0.734、0.592。结论CEUS LI-RADS与MRI LI-RADS分类总的一致性中等,其中LI-RADS-3、4类一致性较强,LI-RADS-M、5类一致性中等。
Objective To assess the interobserver and inter-modalities agreement with two non-invasive diagnostic modalities of hepatocellular carcinoma in high-risk patients:contrast-enhanced ultrasound liver imaging reporting and data system(CEUS LI-RADS)and magnetic resonance imaging liver imaging reporting and data system(MRI LI-RADS).Methods From August 2017 to August 2019,the CEUS and MRI data of patients at high risk for HCC from the Second Affiliated Hospital of Zhejiang University School of Medicine were analyzed retrospectively.A total of 217 lesions in 173 patients were classified according to CEUS LI-RADS v.2017 or MRI LI-RADS v.2018,by 4 blinded independent observers with more than 10 years of experience of CEUS or MRI.Interobserver and inter-modalities agreement was assessed with Cohen′s kappa.Results The interobserver agreement was moderate and comparable for CEUS/MRI LI-RADS category(κ=0.606/0.603),the inter-modalities agreement was moderate for CEUS and MRI LI-RADS category(κ=0.564),LI-RADS 3,M,4 and 5 by two imaging methods showed that the Kappa values were 0.739,0.551,0.734 and 0.592,respectively.Conclusions The total inter-modalities agreement between CEUS and MRI LI-RADS categories is moderate,while the agreements of LI-RADS 3,4 are strong,and LI-RADS M,5 are moderate.
