摘要
目的：本研究采用组织结构声学定量技术检测正常人肝脏组织声学结构定量参数值，分析造成各分组间参数值差异的影响因素。并评估该项技术在肝脏实质超声图像分析的应用价值。方法：本研究选择体检健康者449例，按年龄分为青年组（20～39岁，170例）、中年组（40～59岁，140例）、老年组（60～80岁，139例），且每组中分男、女性别组。应用具备ASQ技术的Aplio 500超声诊断仪录取肝脏组织ASQ图像，脱机后应用ASQ分析软件对图像进行声学结构定量分析，计算相应的Mode（众数）值、Average（平均值）值和SD（标准差）值。结果：各年龄组间中年组和青年组间Average值、SD值均无统计学意义（P>0.05），老年组Average值、SD值均明显高于中年组和青年组（P<0.05）；Mode值差别无统计学意义（P>0.05）。各性别组间青年组性别间Mode值、Average值、SD值均无统计学意义（P>0.05）。中年组性别间SD值无统计学意义（P>0.05），中年男性Average值、Mode值均明显高于中年女性（P<0.05）。老年组性别间Mode值差别无统计学意义（P>0.05）。老年女性Average值、SD值均明显高于老年男性（P<0.05）。结论：应用组织结构声学定量技术可以对正常人肝脏进行定量评价，进行组织声学结构定量评估时需考虑年龄及性别因素。
Abstract
Objective: To evaluate the diagnostic value of acoustic structure quantification(ASQ) technology in normal adult liver and to analyze the factors that make the differences between the groups. Methods: Four hundred and forty-nine healthy subjects, who underwent quantitative assessment of liver tissue using the acoustic structure quantification technology, were included in the study and according to gender and age were divided into elderly group(60~80 years old), middle-aged group(40~59 years old), and youth group(20~39 years old). In each group were further divided into male and female group. ASQ quantitative parameters were analyzed, including Mode, Average, and SD. Results: There was no significant difference in Mode among the age groups(P>0.05). There were significant differences in Average and SD between female elderly group and male elderly group(all P<0.05). There were significant differences in Average and Mode between female middle-aged group and male middle-aged group(all P<0.05). There were no significant differences in Mode, Average and SD between female youth group and male youth group(all P>0.05). Conclusion: Age and gender factors play important roles in the assessment of ASQ technology.
