This study investigated the feasibility of multiparametric magnetic resonance imaging (MRI) (IVIM, DKI, BOLD) to evaluate the liver regeneration process after 70% hepatectomy in rats. MRI examination and pathologic samples were performed at multiple time-points. The results showed that D, D*, FP, MD, MK, and T2* can be used to monitor the microstructural changes after surgery, and D* and MK were significantly correlated with proliferative indexes of Ki - 67 and hepatocyte size. This suggests that multiparametric MRI can aid in noninvasive radiologic monitoring of liver regeneration and intrinsic microstructure evaluation
