轻度支气管扩张的高分辨CT诊断

High resolution CT diagnosis of mild bronchiectasis

目的:探讨MSCT薄层高分辨重建对诊断轻度支气管扩张的价值。方法:对25例咳嗽、咳痰、痰血、咯血、反复肺内感染的患者进行CT常规扫描(层厚10 mm),再对可疑位置的支气管及周围征象进行薄层高分辨重建(层厚1.25 mm)。结果:确诊支气管扩张症19例,在19例支气管扩张中6例为轻度支气管扩张;其中4例疑似肺结核病人明确为支气管扩张。其余6例患者中,3例为正常;1例为早期中央型肺癌导致咯血;1例肺泡内可见少量积血,未见确切支气管扩张征象;1例确诊为肺结核。结论:在MSCT常规扫描基础上行薄层高分辨重建对诊断轻度支气管扩张十分有效。

Objective：To explore and discuss the diagnosis value of MSCT thin-slice high resolution reconstruction on mild bronchiectasis. Methods： Practice regular CT scanning （10 mm） on 25 patients with coughing, expectoration, hemoptysis production, hematemesis and lung infection repeatedly. And practice thin-slice high resolution reconstruction in the suspicious positions of bronchus and signs around （ 1.25 mm）. Results ： It is confirmed that there are 19 cases of bronchiectasis. 6 of them are mild one, and 4 of them are suspected tuberculosis pa- tients with bronchiectasis. Among the 6 patients, 3 of them are normal, while the others are early central lung cancer with hematemesis. There is a small amount of alveolar hemorrhage without obvious sign of bronchiectasis and tuberculosis. Conclusion ： It is effective to practice MSCT regular scanning plus thin-slice high resolution reconstruction in the diagnosis of mild bronchiectasis.
