摘　　要：目的探讨声触诊组织量化(virtual touch tiSSue quantification,VTQ)技术在早期肝硬化诊断中的价值。方法利用声触诊组织量化技术对3组共122例受检者(慢性乙型肝炎组51例,早期肝硬化组39例,健康对照组32例)肝脏右叶进行检查,测得感兴趣区肝脏VTQ值。结果 3组受检者肝脏VTQ值有显著差异(P=0.000);VTQ技术区分慢性乙型肝炎组和早期肝硬化组的VTQ值cut off值为1.84 m/s,其诊断早期肝硬化的敏感度为94.9%,特异度为84.3%。结论 VTQ技术能够定量反映肝组织硬度信息,对诊断早期肝硬化有重要的价值。Objective To analyse the application value of virtual touch tissue quantification（VTQ） technique in diagnosising early liver cirrhosis. Methods The right lobes of liver of 122 people in three groups （51 patients with chronic hepatitis B,39 patients with early liver cirrhosis and 32 healthy controls） were checked by VTQ technique in order to measure values of VTQ in regions of interest. Results The VTQ values were significantly different in three groups（P=0. 000） ;The VTQ value of 1.84 m/s was used as cut-off value to distinguish between chronic hepatitis B and early liver cirrhosis,The sensitivity to diagnose early liver cirrhosis was 94.9% and its specificity was 84.3%. Conclusions VTQ technique could quantitatively reflect liver tissue stiffness information,which had important value to diagnose early liver cirrhosis.
