92例眼眶异物的影像诊断价值分析

An evaluation of the imaging diagnosis of foreign body in orbit in 92 cases

目的比较X线平片、平扫CT及B超对眼眶异物的诊断价值。方法随机选择92例经过手术或临床证实的眼眶异物病例,回顾分析异物在3种检查中的表现。结果异物在3种检查中均可显像的有57例,仅是CT和超声显像有6例,仅是CT显像2例,仅是超声显像15例,仅是平片显像6例,全部检查都没有显像的有6例。结论3种检查对异物诊断各有其优点缺点,临床医生应该综合应用。

Objective To evaluate the image characteristics of X - ray plain film, CT, and B - mode ultrasound in the diagnosis of orbital foreign body. Methods Imaging findings of 92 cases of orbital foreign body were retrospectively analyzed. All cases were proved by surgery or clinic. Results In 57 cases out of 92, foreign body was shown on all three methods; revealed only on CT and B -mode ultrasound in 6 cases; found on CT in 2 cases; only displayed on B -mode ultrasound in 15 cases; and visualized on X -ray plain film in other 6 cases, while in 6 cases the foreign body could not be found with any examinations. Conclusion X - ray plain film, CT, and B - mode ultrasound have respective advantages in diagnosis of orbital foreign body, and should be combined in clinical application.
