Inter-observer Agreement of Liver Biopsy and Liver MR Elastography

Although invasive, liver biopsy has been regarded as the reference method for liver fibrosis diagnosis. Liver MR Elastography is a noninvasive method for liver fibrosis diagnosis. In this study, we compared the inter-observer agreement of two biopsy interpretations with that of two liver MRE interpretations. We found that liver MRE had greater inter-observer agreement than liver biopsy, MRE_ICC = 9544, Biopsy_ICC = 0.8858.
