摘要：

目的  应用声速匹配技术估测健康成人腹部脏器的声速（SV）参考值并探讨影响因素。方法  由两名操作者分别对81名健康志愿者的肝、胰腺、脾、双侧肾实质及肾窦进行SV测定，首先获得相应的区域速度指数，进而得到SV值。估测各脏器SV正常参考值并分析受检者年龄、体质量指数与SV的相关性。结果  两位操作者所测得的相应脏器SV的差异无统计学意义(P>0.05)。肝左叶和肝右叶间及肾实质与肾窦间SV的差异有统计学意义(P<0.05)。相关性分析结果显示：腹部脏器的SV与受检者的年龄和体质量指数均呈负相关。结论  声速匹配技术有望通过定量评价为腹部脏器疾病的超声诊断提供有价值的信息。

Abstract:

Objective  To estimate reference values of sound velocity (SV) of  abdominal organs of healthy adults by sound speed correction (SSC) technology and investigate relative influencing factors. Methods  A total of 81 healthy volunteers underwent SV measurements of liver, pancreas, spleen, bilateral renal parenchyma, and renal sinus by two operators. Zone speed indexes were acquired and SV values were calculated. Normal SV reference values of organs were estimated and the correlation of age, body mass index, and SV was analyzed. Results  The difference of SV values of organs measured by two operators was not statistically significant (P>0.05). The differences of SV values between left and right lobes of liver and between renal parenchyma and renal sinus were statistically significant (P<0.05). Results of correlation analysis showed that both age and body mass index were negatively correlated with SV values of organs. Conclusion  SSC technology is expected to provide valuable information for ultrasonic diagnosis of abdominal organ diseases by quantitative assessment.
