目的 评价实时组织弹性成像(RTE)弹性特征量诊断肝纤维化程度的相关关系.方法 76例乙肝患者肝纤维化程度分为F0～F4期,同时进行RTE检查,获取弹性特征量:包括应变均值(MEAN)、标准偏差(SD)、蓝色领域％ (AREA)、复杂度(COMP)、峰度(KURT)、偏度(SKEW)、对比度(CONT)、均等性(ENT)及杂乱度(IDM).结果 F0/F1比较无显著性差异,F1/F2,F1/F3,F1/F4,F2/F3或F3/F4比较,部分弹性特征量有显著性差异.结论 RTE弹性特征量可能反映肝纤维化的程度,可望成为肝纤维化程度的无创性诊断方法之一.%Objective To assess the relationship of tissue elasticity obtained from Real-time Tissue Elastography (RTE) with liver fibrosis. Methods Liver fibrosis of 76 patients with chronic hepatitis B were divided into F0~F4. In the same time, RTE were performed to get he values for tissue elasticity, including Average relative strain value (MEAN), Standard deviation of relative strain value (SD), Area ratio of low-strain region (AREA),Complexity (COMPKKurtosis (KURTKSkewness (SKEW) Xontrast(CONT) .Entropy (ENT) and Inverse difference moment (IDM). Results There was no significant difference between F0/F1 in all values for tissue elasticity, and significant difference between F1/F2, F1/F3, F1/F4, F2/F3 or F3/F4 were observed in parts of values of tissue elasticity. Conclusions The values for tissue elasticity may reflect the degree of liver fibrosis, and may be a new non-invasive method for diagnosing liver fibrosis.
