Retrospective comparison of EASL 2018 and LI-RADS 2018 for the noninvasive diagnosis of hepatocellular carcinoma using magnetic resonance imaging
Hepatology International(2019)
摘要
Purpose We compared the diagnostic performances of the European Association for the Study of the Liver (EASL) 2018 and Liver Imaging Reporting and Data System (LI-RADS) 2018 criteria on magnetic resonance imaging (MRI) for the noninvasive diagnosis of hepatocellular carcinoma (HCC) in high-risk patients and evaluated the difference in diagnostic value between MRI with extracellular contrast agents (ECA-MRI) and MRI with hepatobiliary agents (HBA-MRI). Methods This study included 382 observations from 298 patients at high risk for HCC who underwent preoperative multiphasic contrast-enhanced MRI between January 2015 and December 2016. Two readers assessed all observations according to the EASL 2018 and LI-RADS 2018 criteria, and the per-observation diagnostic performances were compared. Results On ECA-MRI, the LR-5 category of LI-RADS 2018 showed significantly higher sensitivity (78.9% vs. 71.5%, p = 0.005) and accuracy (81.7% vs. 75.0%, p = 0.003) for the diagnosis of HCC than the EASL 2018. On HBA-MRI, the diagnostic performances of the EASL 2018 and LR-5 of LI-RADS 2018 were not significantly different. When using EASL 2018, no statistically significant differences were observed in the diagnostic performances between ECA-MRI and HBA-MRI; however, when using the LR-5 of LI-RADS 2018, ECA-MRI had a higher sensitivity (78.9% vs. 67.5%, p = 0.029) than HBA-MRI. Conclusions On ECA-MRI, the LR-5 category of LI-RADS 2018 provides better sensitivity and accuracy than the EASL 2018 for diagnosing HCC. EASL 2018 provides comparable diagnostic performances between ECA-MRI and HBA-MRI, but the LR-5 category of LI-RADS 2018 provides better sensitivity on ECA-MRI than on HBA-MRI.
