目的 通过对３６ 例支气管扩张的胸片、支气管碘油造影和ＣＴ的对比研究，探讨支气管扩张的最佳诊断方法。方法 选取经支气管碘油造影证实的支气管扩张症３６ 例，全部病例均有Ｘ线与ＣＴ检查资料，采用双盲法阅片，分析比较胸片、支气管碘油造影和ＣＴ征象。结果 全部病例ＣＴ 扫描与支气管碘油造影诊断基本一致，诊断为支气管柱状扩张２０ 例，曲张扩张６ 例，囊状扩张２ 例，混合型扩张８ 例。结论 ＣＴ 对支气管扩张诊断比较优越，并能取代支气管造影。
OBJECTIVE To investigate the best diagnosis method of bronchiectasis by comparing 36 cases of bronchiectasis, radiography and CT. Methods Thirty-six cases of bronchiectasis confirmed by bronchogenic lipiodol were selected. X-ray and CT examinations were performed in all cases. The double-blind radiographs were used to compare the results of chest radiography, bronchial lipiodol and CT. Results CT scan in all cases was basically consistent with the diagnosis of bronchial lipiodol. Diagnosis of bronchial columnar distension in 20 cases, varicose vein expansion in 6 cases, cystic dilatation in 2 cases, mixed dilation in 8 cases. Conclusion CT diagnosis of bronchiectasis superior, and can replace bronchography.
