【Abstract】 Objective To analyze the change of scatter signal of hepatic parenchyma of children infected with schistosome and to deduce the degree of hepatic fibrosis by using integrated backscatter (IBS). Methods We analyzed the IBS of 14 normal children and 17 children who were infected with Schistosome and compared the IBS of the two group on computer. Results We compared the value of IBS from the sample of normal hepatic parenchyma with that from hepatic parenchyma infected with schistosome, the value of normal group was higher than that of infected group. The value of IBS in hepatic fibrosis nodes was much higher than the other parts. Conclusion The value of IBS can reflect the pathological changes of hepatic parenchyma of children inflected with schistosome and predict the degree of hepatic fibrosis.更多还原
