Diagnostic performance of 2D shear wave elastography in predicting liver fibrosis in patients with chronic hepatitis B and C: a histopathological correlation study.

2D-SWE is reliable and accurate for the diagnosis of liver fibrosis. In selected patients, 2D-SWE may be useful in reducing the need for liver biopsy when staging fibrosis. Further studies in larger prospective series are needed to confirm these results and determine the most appropriate cut-off values for each stage of liver fibrosis.
