Portal vein embolization (PVE) is often performed before liver tumor resection, to induce hypertrophy of the anticipated liver remnant and reduce the complications after partial liver resection. The perfusion changes of the embolized and non-embolized liver segments are of great interest. Intravoxel incoherent motion (IVIM) is a component of the diffusion weighted signal model that allows for separating estimation of perfusion. Estimation of IVIM from diffusion weighted imaging which may provide a unique way to measure the perfusion of liver tissue. This study aimed to test the intra-observer repeatability of IVIM and parameters change after PVE used a pig model.
