Abstract: Ultrasonic elastography is a new non-invasive technology to assess the degree of liver fibrosis
by measuring liver stiffness. This article is based on the current development situation of elastography
technology at home and abroad. We summarized the application of the technology scope, diagnostic value,
different threshold level, advantages and disadvantages in practical application. Especially in recent years,
ultrasonic elastography developed rapidly, which has made significant progress in diagnosis and evaluation
of liver fibrosis. This method was initially applied and validated in chronic hepatitis C, and then used in other
chronic liver diseases such as non-alcoholic fatty liver disease and chronic hepatitis B, so the need for liver
biopsy decreased.
