摘要
目的探讨超声背向散射积分幅差法定量诊断脂肪肝的价值。方法用配置AD装置和声学定量分析系统的超声诊断仪对87例脂肪肝患者及20例正常对照人员的肝脏近、远声场背向散射积分(IBS)值幅差进行定量分析。结果脂肪肝患者肝实质回声近、远声场IBS值幅差明显大于正常肝脏(P<0.05)。结论超声背向散射幅差法可作为一种新的量化指标用于脂肪肝的定量诊断。
Objective To detect the value of difference of ultrasonic integrated backscatter（IBS） on quantitative diagnosis of diffuse fatty liver. Methods The IBS differences between near fields and far fields of liver in 87 patients with diffuse fatty liver and 20 normal people were measured and analysed quantitatively by acoustic quantitative analysed system. Results The IBS differences between near fields and far fields of liver in patients with fatty liver were much bigger than those in control group（ P 〈 0.05 ）. Conclusions The method of IBS difference is a new quantitative index,which can be used to diagnose fatty liver quantitatively.
