【摘要】：目的探讨声触诊组织定量技术检测正常儿童肾皮质弹性的价值。方法超声诊断仪检测600名健康儿童双侧肾脏皮质SWV值,比较不同年龄、性别、侧别间SWV值差异;对372名儿童同时测量双侧肾脏大小(以肾脏长轴最大径线作为肾脏长度,以此值为参考),比较不同肾脏大小SWV值差异;对101名儿童分别测量双侧肾脏中极和下极SWV值,比较不同取样部位SWV值差异;对31名5~6岁儿童分别用4C-1凸阵探头和9L-4线阵探头测肾脏SWV值,比较不同探头间肾脏SWV值差异。结果健康儿童不同年龄、肾脏大小、取样部位间肾皮质SWV值差异均有统计学意义(P均0.05);而不同性别、侧别、探头间肾皮质SWV值差异均无统计学意义(P均0.05)。结论 ARFI可用于儿童肾脏弹性检测。
[Abstract]:Objective to evaluate the value of acoustic palpation tissue quantitative technique in the detection of renal cortex elasticity in normal children. Methods the SWV values of bilateral renal cortex in 600 healthy children were measured by ultrasonic diagnostic instrument, and the differences of SWV values among different age, sex and side were compared. In 372 children, the size of bilateral kidneys was measured simultaneously (taking the maximum length of kidney axis as the reference, the SWV values of different renal sizes were compared, and the SWV values of the middle and lower poles of bilateral kidneys were measured in 101 children, respectively). The SWV values of kidney were measured by 4C-1 convex array probe and 9L-4 linear array probe in 31 children aged 5 to 6 years, and the difference of renal SWV value between different probes was compared. Results the healthy children were of different ages and kidney size. There were significant differences in SWV values of renal cortex between different sampling sites (P < 0.05), but there were no significant differences in SWV values of renal cortex between different sex, side and probe. Conclusion ARFI can be used to detect renal elasticity in children.
