Group Intervention Description CT-image guidance CT-image guidance Previously acquired portal venous phase of CT datasets and intra-operative CT datasets were registered on a dedicated workstation. The selected volume of interest of the CT-image showing portal vein vasculature was overlaid onto the fluoroscopic display as real-time 3D CT-image guidance during the procedure. CO2 portography CO2 portograms guidance two two-dimensional (2D) CO2 portograms
