目的探讨食道颈段异物高频彩色多普勒超声图像特征。方法对6例食道颈段异物高频彩色多普勒声像图进行回顾性分析,并与胃镜、X线检查结果比较。结果食道颈段异物超声表现为食道腔内或壁内长条状、斑片状或不规则强回声伴后方伴声影,部分后方伴彗星尾征。结论高频彩色多普勒超声检查对食道颈段异物诊断有其特异性,值得推广应用。
Objective To investigate the characteristics of high frequency color Doppler ultrasound imaging of foreign body in esophageal neck. Methods High-frequency color Doppler sonography of 6 cases of esophageal cervical segment foreign bodies was retrospectively analyzed, and compared with gastroscopy and X-ray examination. Results The results of esophageal cervical foreign body ultrasound showed long or lumps in the esophagus or the wall, patchy or irregular hyperechoic with acoustic shadow, part of the rear with comet tail syndrome. Conclusion High-frequency color Doppler ultrasound examination of esophageal cervical foreign body has its specificity, it is worth to promote the application.
