目的探讨高频彩色多普勒超声对足及踝部外伤性病变的诊断价值。方法回顾性分析本院2013年1月~2015年9月收治的疑似足及踝部外伤性病变的47例患者的高频彩色多普勒超声检查结果,观察其声像图改变及特征,并将超声检查结果与MRI、X线检查结果及手术病理结果进行对比分析。结果与手术病理结果比较,高频彩色多普勒超声诊断I型、II型、III型韧带损伤的诊断符合率分别为71.4%、76.9%、80.0%;与MRI检查结果比较,超声诊断肌腱损伤的符合率为93.8%;超声对骨折的诊断结果与X线诊断结果一致性较好。结论高频彩色多普勒超声对足及踝部外伤性病变具有较高的诊断价值,可作为足及踝部外伤的常规影像学检查方法。
Objective To investigate the diagnostic value of high frequency color Doppler ultrasound in the traumatic lesions of the foot and ankle. Methods The results of high-frequency color Doppler ultrasonography in 47 patients with suspected foot and ankle traumatic lesions admitted to our hospital from January 2013 to September 2015 were retrospectively analyzed. The changes and characteristics of sonography were observed The results of ultrasound and MRI, X-ray examination results and surgical pathology results were analyzed. Results Compared with the results of surgery and pathology, the diagnostic coincidence rates of type I, type II and type III ligament injuries by high-frequency color Doppler ultrasound were 71.4%, 76.9% and 80.0% respectively. Compared with MRI findings, ultrasound diagnosis of tendon injury The coincidence rate was 93.8%. The diagnostic accuracy of ultrasonic diagnosis of fractures was consistent with that of X-ray diagnosis. Conclusion High-frequency color Doppler ultrasonography has high diagnostic value in the foot and ankle traumatic lesions, and can be used as a routine imaging examination of foot and ankle trauma.
