Kang JH, Choi SH, Lee JS, et al. - Researchers conducted a systematic review and meta-analysis to determine the interreader agreement of liver imaging reporting and data system (LI-RADS) on MRI and to ascertain the sources of heterogeneity between the reported results. The data extraction was performed by two independent reviewers. The analysts recognized and reviewed the original articles describing the interreader agreement of LI-RADS using MRI. Using the random-effects model, the meta-analytic pooled intraclass association coefficient for lesion size and kappa value (κ) for major features (arterial-phase hyperenhancement, nonperipheral washout [WO], enhancing capsule) and LI-RADS categorization were calculated. Sensitivity analysis and meta-regression analysis were performed to explore the cause of study heterogeneity. The results showed that LI-RADS demonstrated overall substantial interreader agreement for major features and the category on MRI, but revealed heterogeneous results between studies.
