主 题：Liver Shear wave elastography Propagation velocity Viscoelasticity Artifact Ultrasound
摘 要：Shear wave elastography(SWE)is now becoming an indispensable diagnostic tool in the routine examination of liver *** particular,accuracy is required for shear wave propagation velocity measurement,which is directly related to diagnostic *** is generally accepted that the liver shear wave propagation velocity reflects the degree of fibrosis,but there are still few reports on other factors that increase the shear wave propagation *** this study,we reviewed such factors in the literature and examined their *** SWE measures propagation velocity based on the assumption that the medium has a homogeneous structure,uniform density,and is purely ***,the measurement is subject to *** other(confounding)factors that we routinely experience are primarily:(1)Conditions that appear to increase the viscous component;and(2)Conditions that appear to increase tissue ***,the former includes acute hepatitis,congested liver,biliary obstruction,etc,and the latter includes diffuse infiltration of malignant cells,various storage diseases,tissue necrosis,*** any case,it is important to evaluate SWE in the context of the entire clinical picture.
