| 目的 应用背向散射积分(IBS)分析血吸虫感染儿童肝实质散射信号的变化,推断肝组织纤维化的程度。方法 对14例正常儿童肝脏及17例血吸虫感染儿童的肝脏进行背向散射积分联机分析,比较两者IBS值。结果 正常组肝实质取样区与血吸虫病肝实质比较IBS值正常组高于血吸虫病组(P<0.01),血吸虫病肝纤维化结节部位IBS值明显高于非结节部位(P<0.01)。结论 背向散射积分的变化能反映儿童血吸虫病肝实质病变,提示纤维化程度。 |

| 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. |
