  1. Notes: Time of scan is the time of MRI scan after CCl4 injection. Week 6 is the last time point with CCl4 injection. From week 7 to 12, the CCl4 has been withdrawn. P1 and P2 values denote the significance level in the Mann-Whitney U test between T1rho values in this time point and T1rho values in baseline and adjacent previous time point, separately
