健康成人颈段气管的体外高频超声影像及测量分析

Extracorporeal high-frequency ultrasound imaging in cervical trachea of the health adult and diameter measurement analysis

目的探讨健康成人颈段气管的体外高频超声影像特点,为开展体外超声在检测颈段气管病变应用作前期研究。方法应用体外高频超声观察120例健康成人颈段气管结构的声像表现,并对气管环T1-T4的内外横径、气管环厚度、相邻气管环间距进行测量和统计学分析。结果 120例志愿者均获得了颈段气管前、侧壁声像图,以及气管环T1-T4内外横径、气管环厚度、相邻气管环间距测值。结论体外高频超声可以清晰显示气管形态和细微支撑结构,并进行部分径线测量,有望成为评估颈段气管病变的一种有价值的辅助手段。

Objective We investigated features of the healthy adult cervical tracheas in order to studying cervical tracheal lesions by extracorporeal high-frequency ultrasound EHFUS. Methods EHFUS examination of the trachea was performed in 120 asymptomatic adult volunteers. We observed imaging features of the healthy adult cervical tracheas,and measured TRID, TRED,TRTh and TRAS to analysis. Results The cervical tracheal anterior and side wall ultrasonograms,and measurements were obtained in all subjects. Conclusion The cervical tracheal shape and the fine structure of support can be seen in EHFUS,and partly of diameter measurements were obtained. Thus EHFUS may be a valuable assistant method to assess cervical tracheal lesions of support structure.
