Comparison Liver Stiffness Measurement by Transient Elastography and Shear Wave Elastography

摘要

To compare liver stiffness (LS) values measured by transient elastography (TE), 2D-shear wave elastography (2D-SWE) and point shear wave elastography (p-SWE). 90 subjects were examined by Radiology department, Rajavithi hospital, Bangkok, Thailand and data was analyzed by SPSS version 17.0. The results found that the correlation of liver stiffness value between TE and 2D-SWE was the highest with r=0.84 (p-value=0.001). Then the simple linear regression equations for prediction liver stiffness value were LS(TE)=-6.08+2.09LS(2D-SWE) and LS(TE)=2.03+1.12 LS(p-SWE). Using area under receiver operating characteric curve (AUROC) to investigate significant fibrosis and cirrhosis, both shear wave elastography techniques, 2D-SWE and p-SWE, were appropriate to predict fibrosis than significant fibrosis. Furthermore, 2D-SWE was higher performance in prediction significant fibrosis and cirrhosis than p-SWE.
