目的 探讨MSCT扫描在诊断支气 管扩张中的临床价值分析。方法 选取本 院2013年12月-2014年7月经胸外科手术 或呼吸内科随访确诊为支气管扩张的患 者46例，整理比较46例患者X线胸部正侧 位检查与MSCT扫描对支段扩张的检出结 果，分析MSCT扫描对支气管扩张的临床 价值。结果 X线胸部正侧位共检出支气 管扩张个数61(36.31%)个，包括囊状支 气管扩张42个，柱状支气管扩张19个； MSCT扫描共检出支气管扩张141(83.92%) 个，对支气管扩张分型显示优于X线，其 中囊状支气管扩张74个，柱状支气管扩 张23个，静脉曲张型支气管扩张25个， 混合型支气管扩张19个，两组检查方式 对支段扩张的检出个数具有统计学差异 (P<0.05)。结论 MSCT扫描对支气管扩 张的扩张特征、分型及位置显示直观全 面，可作为支气管扩张患者的首选检查 方式。

Objective To explore the clinical value of MSCT scan in the diagnosis of bronchial dilation. Methods 46 cases of patients with bronchiectasis which were diagnosed by operation in the department of chest surgery or follow up by respiratory department in our hospital from December 2013 to July 2014. Compare the result of X-ray examination and MSCT scan, and then analyze the clinical value of MSCT scanning. Results 61 bronchiectasis were diagnosed by X-ray(36.31%), including 42 cystic bronchiectasis, 19columnar bronchiectasis. 141 bronchiectasis were diagnosed by MSCT (83.92%), showing superior to X-rayon bronchiectasis classificatory, including 74 cystic bronchial dilatation, 23columnar bronchiectasis, 25 bronchial type of varicose vein, 19mixed type bronchiectasis. The two groups of inspection methods on the test of bronchiectasis were statistical significance (P<0.05). Conclusion MSCT scan can be used as the first choice for patients with bronchial dilation, and it can be used as the first choice for patients with bronchial dilation.
