摘要
目的:探讨胸部DR及MSCT对气道透X线异物的诊断价值。方法:回顾性分析经术前胸部DR、MSCT诊断并经纤维支气管镜取异物术后证实,并有术后胸部DR复查的93例气道透X线异物病例的临床及影像学资料,将术前胸部DR与术后DR、术前MSCT进行对照,比较术前胸部DR、MSCT显示透X线异物的直接、间接征象和异物定位情况。结果:93例中术前胸部DR有82例显示了透X线异物的直接征象,阳性征象显示率为88.17%;术前MSCT 93例均显示了透X线异物的直接征象,阳性征象显示率为100%。显示异物的间接征象方面两种检查方法无明显差异。术前胸部DR提示异物存在及定位的有91例,术前MSCT提示异物存在及定位的有93例。结论:胸部DR能显示绝大部分透X线异物的直接征象,填补了传统胸部X线检查不能显示异物直接征象的空白,在诊断透X线支气管异物以及异物定位方面均有较高的应用价值。在诊断气管透X线异物方面,MSCT有明显优势。
Objective：To study the value of digital radiography（DR）and multi-slice spiral computerized tomography（MSCT）of chest in detecting intra-tracheobronchial radiolucent foreign body.Methods：Pre-and postoperative DR and MSCT of chest in 93 patients with intra-tracheobronchial radiolucent foreign body were reviewed and analyzed,All patients were confirmed by foreign body extraction via bronchofiberscopy.Direct,indirect imaging findings and localization of intratracheobronchial radiolucent foreign body before and after operation were studied and compared.Results：Of the 93 patients,direct sign of intra-tracheobronchial radiolucent foreign body was assessed in 82patients（88.17%）of chest DR before operation;which was assessed in 93patients（100%）with preoperative MSCT.However,there was no obvious difference in detecting the indirect sign with these two modalities.For the ability of localization of foreign body,91 out of 93 patients were found and localized by preoperative chest DR,and 93 out of 93 patients were found and localized by preoperative MSCT.Conclusion：The direct sign of intra-tracheobronchial radiolucent foreign body can be revealed by chest DR in most of the patients,which is much superior to conventional chest radiography,and have a high application value in the diagnosis and localization of intra-tracheobronchial transluscent foreign body.However,MSCT has obvious advantage in the diagnosis of intra-tracheobronchial radiolucent foreign body.
