目的 评价各种影像检查在支气管扩张诊断中的作用及互补性、优选性。方法 结合手术和病理观察，分析４１ 例支气管扩张患者的影像学资料。结果 Ｘ 线平片显示出多种影像学表现；支气管造影阳性率高达９０－９ ％ ，与手术和病理结果符合率达７２－７％ ；胸部ＣＴ 诊断阳性率为８４－０％ ，与手术和病理结果相一致为５６－０ ％ 。结论 支扩的Ｘ 线影像特点与病理所示支扩性质及其并发症具有一致性；支气管碘油造影和胸部ＣＴ 能明确提示支扩的部位和范围，前者阳性率更高，诊断遗漏较少；但ＣＴ 能显示双侧支气管影像，薄层ＣＴ可明显提高诊断率。
Objective To evaluate the effect and complementarity of various imaging tests in the diagnosis of bronchiectasis. Methods Combined with operation and pathology, 41 cases of bronchiectasis were analyzed. The results of X-ray showed a variety of imaging findings; bronchography positive rate of 90-9%, consistent with the surgical and pathological results of 72-7%; chest CT diagnostic positive rate was 84-0%, and surgery and The pathological results are consistent with 56-0%. Conclusions The characteristics of X-ray imaging with branch expansion are consistent with the nature of branch and expansion as well as its complications. Bronchogenic lipiodol and chest CT can clearly indicate the location and extent of branch expansion. The former has a higher positive rate and less omission of diagnosis ; But CT can show bilateral bronchial image, TLC can significantly improve the diagnostic rate.
