摘　　要：目的　比较研究 4种影像学方法对支气管扩张症 (支扩 )的诊断价值。资料与方法　对 4 2例临床诊断为支扩的患者分别行胸片、常规CT、HRCT及数字减影支气管造影 (DSB)检查。结果　HRCT显示支扩的敏感性为95 % ,特异性为 98% ,假阳性率为 2 % ,假阴性率为 5 % ;HRCT与DSB具有良好的一致性。结论　HRCT较其他影像学方法更具优越性 ;对临床疑为支扩者 ,应胸片后首选HRCT。Objective To evaluate four imaging methods in the diagnosis of bronchiectasis.Materials and Methods Chest film, conventional CT scanning, HRCT scanning and digital subtraction bronchography (DSB) were carried out in 42 patients with clinically-proved bronchiectasis. The results were analyzed, and the sensitivity and specificity of different imaging methods were compared with each other.Results The sensitivity and specificity of HRCT for bronchiectasis was 95% and 98%, respectively. HRCT showed a good agreement with DSB. Conclusion HRCT is superior to other imaging methods in diagnosing bronchiectasis, it should be considered as the first choice for clinically-suspected bronchiectasis patients.
