Intravoxel Incoherent Motion Diffusion Weighted Imaging for Preoperative Evaluation of Liver Regeneration after Hepatectomy in Hepatocellular Carcinoma

To explore whether intravoxel incoherent motion (IVIM) parameters could evaluate liver regeneration preoperatively. A total of 175 HCC patients were initially recruited. The apparent diffusion coefficient, true diffusion coefficient (D), pseudodiffusion coefficient (D*), pseudodiffusion fraction (f), diffusion distribution coefficient, and diffusion heterogeneity index (Alpha) were measured by two independent radiologists. Spearman’s correlation test was used to assess correlations between IVIM parameters and the regeneration index (RI), calculated as 100
