Liver regeneration of residual right lobe after left lateral sectionectomy in living liver donors: a pilot study based on IVIM and T2* mapping MRI

This study investigated the dynamic changes of residual right liver lobe after left lateral sectionectomy (LLS) and the potential value of IVIM and T2* mapping in evaluation of liver regeneration in living liver donors. All IVIM indexes of right liver lobe showed no obvious changes after surgery, but liver T2* values increased significantly at 2 weeks after surgery, and kept increasing gradually from week 2 to 8. Liver T2* values correlated moderately with liver volume, it may be a good substitute to liver volume in evaluating liver regeneration
