Synopsis: The purpose of this study was to explore the evaluation value of liver fibrosis staging and hepatitis activity of chronic hepatitis B based on multi-sequence MRI radiomics model. Unenhanced T2WI, T1WI and Gd-EOB-DTPA enhanced T1WI, including AP, PP, TP and HBP, were acquired. And a multi-sequence MRI radiomics model were built. We used receiver operating characteristic (ROC) curves for the diagnostic performance of each sequence and the combination of these six sequences in the training set and validated with the validation set. The models combined with six sequences performed the best.
