The goal of our study was to assess the value of qualitative and quantitative texture features on gadoxetic-acid enhanced MRI compared to blood tests for the detection of liver allograft fibrosis. We found that quantitative texture analysis and laboratory FIB-4 score exhibited complementary information for prediction of fibrosis stage, while qualitative MRI features were only valuable for identifying advanced fibrosis/cirrhosis.
