Intraobserver and interobserver variability in the estimation of liver fibrosis with ShearWave elastography in chronic liver disease: A proposition for standardization through a m…

Purpose: To estimate Intra-Inter Observer Variability (Ia/IeOVar) of measurements of liver fibrosis using ShearWave Elastography (SWE) and to propose efficient ways for an appropriate estimation of fibrosis in cirrhotic patients. Material and methods: We studied 112 cirrhotic patients using SWE. All patients had liver biopsy performed in period not exceeding ± 4 months from US examination. A Transient Elastography TE (Fibroscan) examination has been performed to 82 of those patients in a period not exceeding ± 1 month from US/SWE examination. All patients had US examination and SWE of the liver performed by two…
