Early prediction of remnant liver growth after portal vein embolization (PVE) would enable earlier surgery in patients with liver malignancies and thus decrease the risk of tumor progression. Portal blood flow after PVE holds the potential to be an important predictor for hypertrophy of the non-embolized segments. We demonstrated the feasibility of 4D flow MRI quantification of portal blood flow before and after PVE in a porcine model. Flow changes immediately after PVE were predictive of the change in liver volume 2 weeks post PVE in both the embolized and non-embolized liver lobes.
