Journal of Clinical and Translational Hepatology 2014年第2期2卷 110-116页

作者： Expert Panel on Liver Stiffness measurement department of Infectious Disease and Hepatology Unit Nanfang Hospital Southern Medical University Guangzhou 510515 China Liver Research Center Beijing Friendship Hospital Capital Medical University Beijing 100050 China

Liver fibrosis evaluation is pivotal for treatment decisions and prognosis assessment in patients with chronic liver disease. Liver transient elastography (TE) is a newly developed non-invasive technique for diagnosis of liver fibrosis. It can assess the state of liver fibrosis by liver stiffness measurements, and offers better performance for the diagnosis of liver cirrhosis than serum biological markers. It has now been approved for clinical use in China. The aim of this review is to provide a guide for clinicians to apply this technique appropriately. The recommendations are made under the auspices of China Foundation for Hepatitis Prevention and control, and have been prepared by a panel experts, who have reviewed and summarized the clinical studies on TE in order to develop these recommendations.
