儿童正常阑尾的高频超声显像分析

Diagnosis of Children Normal Appendix by High-frequency Ultrasound

目的:应用高频超声,观察分析儿童正常阑尾的显示率及声像图特点。方法:选择无腹痛症状的儿童56例作为正常组,选择阑尾炎患儿46例作为对照组,采用高频超声进行检查,分析对比正常阑尾的声像图表现。结果:儿童正常阑尾显示率为78.6%。正常阑尾与阑尾炎比较在壁厚、直径、可压缩性、彩色血流显像等方面差异均有显著。结论:高频超声可以显示儿童正常阑尾,认识正常阑尾的超声征象对于阑尾炎的鉴别有重要意义。

Objective To evaluate the frequency of depiction with high-frequency ultrasound of the children normal appendix and to evaluate the ultrasound appearance of the normal appendix. Methods To select 56 children which have no abdominal pain as normal group, and 46 children with appendicitis as control group. To analyze and compare the appear ance of normal appendix using high-frequency ultrasound. Results 78.6 % of the normal appendix of children with ultrasound is depicted with ultrasound; To compare with appendicitis, normal appendix are difference in outer diameters, mural thickness, compressibility, and color Doppler flow. Conclusion The results of this study show that chidren normal appendix can be depicted with high-frequency ultrasound and .It is very important to recognize the ultrasound features of normal appendix for the discrimination of appendicitis.
