This study investigated the effectiveness and feasibility of shear wave elastography ((sound touch elastography) STE and (shear wave elastography) SWE) and visual transient elastography (ViTE) in the noninvasive quantitative diagnosis of liver fibrosis in chronic liver disease (CLD). Patients and Methods: A total of 106 patients with CLD underwent STE, SWE and ViTE elastography evaluation. The Young's modulus of the three elastography was valuated and the diagnostic performances of the three techniques for liver fibrosis staging were compared. The area under the receiver operating curve (ROC) for the diagnosis of liver fibrosis was compared. The final diagnosis was based on the histological findings on the liver biopsy. Results: 1) The correlation between ViTE and SWE, ViTE and STE, SWE and STE stiffness values were 0.72, 0.75, 0.75 (P<0.001). 2) The relationship between the results of each elastography technique and the stage of pathological liver fibrosis showed that the more severe the liver fibrosis was, the higher the stiffness value was (all P <0.001). 3) When the three elastography techniques were used to detect the degree of liver fibrosis in different pathological stages, there was no statistical difference in the stabilities of the boxplots. 4) The ROCs of the three elastography techniques (ViTE, SWE and STE) were 0.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
