Noninvasive assessment of liver disease—measurement of hepatic fibrosis using tissue strain imaging

Abstract

The development of hepatic fibrosis in patients with liver disease is associated with an increased risk of liver cancer. Assessing the degree of hepatic fibrosis is therefore one of the most important factors in treatment planning. Liver biopsy is commonly performed to assess hepatic fibrosis, but this method is associated with complications such as hemorrhage. Recently, a number of studies on the noninvasive assessment of hepatic fibrosis have appeared in the literature. The present study was conducted to determine whether an easily performed myocardial examination technique can also be applied to the assessment of hepatic fibrosis. The statistical software Minitab, which performs hypothesis testing based on the P value, was used for statistical analysis. The mean strain values were 0.26 in the normal adult group, 0.155 in the chronic hepatitis group, and 0.058 in the cirrhosis group. Statistically significant differences were observed between the groups. The results of the present study suggest that noninvasive tissue strain imaging may become the method of choice for assessing hepatic fibrosis in routine clinical practice.
