Abstract

In chronic hepatitis diagnosis, shear wave elastography is utilized for evaluating fibrosis progression. It is expected that the accuracy will be improved by measuring the viscosity in addition to the elasticity. However, the shear wave dispersion in analyzing liver viscosity is affected by both viscosity and fibrous structure. In order to quantitatively evaluate hepatic fibrosis, we evaluated the effect of liver fibrous structure changes on the shear wave dispersion by using simulation model.
