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.
