文摘

The research by ARFI technology is focused on steatosis without fibrosis. ARFI elastography offers good diagnostic accuracy in evaluating the normal rat liver and rat liver with steatosis. The SWV measurements have no significant difference between the grades of steatosis. The early grade of inflammation activity does not significantly affect the SWV measurements.
