摘要
The invention relates to the field of early non-invasive diagnosis, and specifically, to a method of determining a virtual hepatic venous pressure gradient. The method comprises: constructing a 3-dimensional (3D) hepatic vein-portal vein model; establishing a finite element division mathematical model; and applying fluid dynamics to compute and simulate a virtual hepatic venous pressure gradient (vHVPG). The method optimizes and provides a more complete 3D hepatic vein-portal vein model, finite element division, and fluid dynamic simulation computation, constructing and validating a new vHVPG determination technology providing better diagnosis, providing a safe, non-invasive, accurate, and quantitative method for early non-invasive diagnosis of a portal vein high pressure patient.
