Effect of Ultrasound Elastic Imaging and Contrast-enhanced ultrasound in the Evaluation of Hepatic Fibro-sis in Patients with Chronic Hepatitis B / 实用医学杂志

ABSTRACT

Objective To evaluate the effect of ultrasound elastography and radiography in the assessment of hepatic fibrosis in chronic hepatitis B patients. Methods Seventy patients with chronic hepatitis B were en-rolled in our hospital from August 2014 to August 2016. Liver ultrasonography was performed in all patients. HAVTT1 and HAVTT2 were measured by visual method. SWV was measured by ultrasonic elasticity imaging. Re-sults With the increase of liver fibrosis,SWV test also increased,while HAVTT gradually shortened.The correct rates of HAVTT1 and HAVTT2 and SWV in the diagnosis of liver fibrosis were 72.36%,76.84% and 89.78%.The diagnostic accuracy of SWV was higher than that of HAVTT1 and HAVTT2,the difference was statistically sig-nificant(P<0.05).Conclusion Acoustic contrast measurement of HAVTT1 and HAVTT2 can reflect the chang-es of liver microcirculation,which is helpful to distinguish liver cirrhosis,fibrosis and no fibrosis. The measure-ment of SWV can reflect the difference of texture hardness of liver,which can be used as a kind of judgment on the degree and effect of hepatic fibrosis new method.
