摘　　要：近年来,脂肪肝已成为我国最常见的慢性肝病,若长期忽视则易引发肝炎、肝纤维化、肝硬化甚至肝功能衰竭及肝癌,增加其相关死亡率。剪切波弹性成像(SWE)作为定量评估肝脏硬度和疾病分期的首选影像学检查方法之一,却在量化肝脏弹性时忽略了组织黏性,对炎症或脂肪变性等慢性肝病患者的评估存在一定局限性。剪切波频散成像(SWD)基于SWE发展而来,可评估弥漫性肝脏疾病中与组织黏性相关的剪切波频散度斜率,其在SWE模式下自动激活,定量评估肝脏组织的弹性和黏性,能更精准地检测肝脏疾病的分类及分期,为临床诊断提供更多依据。本文就SWD在肝脏弥漫性病变和肝脏局灶性病变术前诊断中的应用进展进行综述。In recent years,fatty liver has become the most common chronic liver disease in our country.If ignored for a long time,it is likely to cause diseases such as hepatitis,liver fibrosis,cirrhosis,and even liver function failure and liver cancer,increasing the related mortality rates.Shear wave elastography(SWE)is one of the preferred imaging methods for quantitative assessment of liver stiffness and disease staging,it ignores the tissue viscosity when quantifying liver elasticity,which has a certain limitations in evaluating patients with chronic liver disease such as inflammation or steatosis.Shear wave dispersion(SWD)is an imaging technique developed based on SWE,which can evaluate the slope of shear wave dispersion related to tissue viscosity in diffuse liver disease.It can be automatically activated in SWE mode to quantitatively evaluate the elasticity and viscosity of liver tissue.The application of SWD can more accurately detect the classification and staging of liver lesions,providing more basis for clinical diagnosis.This article reviews the application progress of SWD in preoperative diagnosis of diffuse and focal liver lesions.
