There was no statistically significant difference in flow velocity, volume rate, axial-WSS of portal system when compared among different CS. Measurements from the two observers matched well with each other.
Figure 1 Segmentation image (A). Visualization module (B), placed measuring planes at the proximal, middle and distal of the PV, perpendicular to the vascular section, flow and WSS were measured. Functional module (C), placed reference plane at the origin of the PV, measuring planes were placed at the proximal, middle and distal of the PV to measure the pressure.
