Abstract:
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.
