To assess the accuracy of computed tomography (CT) in the evaluation of bronchiectasis, we performed thin-section CT in 36 patients with clinical findings suggestive of this diagnosis. CT was performed with 1.5-mm section thickness and 10-mm intersection spacing. Bilateral (eight patients) and unilateral (28 patients) bronchograms were obtained. CT and bronchographic findings were correlated in 44 lungs. In 15 lungs no bronchiectasis was observed on CT scans and bronchograms. In 25 lungs both examinations accurately indicated the presence and extent of bronchiectasis. In two lungs the extent of disease was underestimated on CT, which failed to indicate bronchiectasis in one segment of the affected lobe. In one case CT findings suggested focal bronchial disease, but the lung was misinterpreted as not bronchiectatic; the bronchogram showed cylindric bronchiectasis. In one case CT disclosed cylindric bronchiectasis in a lobe that was bronchographically normal, but in this case the bronchogram was probably misinterpreted as false negative. In two cases lung findings were better visualized on CT scans than on bronchograms. It is concluded that thin-section CT is an accurate procedure in the recognition of bronchiectasis.
为评估计算机断层扫描（CT）在支气管扩张评估中的准确性，我们对36例有提示该诊断临床症状的患者进行了薄层CT检查。CT扫描层厚为1.5毫米，层间距为10毫米。获得了双侧（8例患者）和单侧（28例患者）的支气管造影图像。对44个肺的CT和支气管造影结果进行了对比。15个肺在CT扫描和支气管造影中均未观察到支气管扩张。25个肺的两项检查均准确显示了支气管扩张的存在及范围。2个肺的病变范围在CT上被低估，CT未能显示受累肺叶一个节段的支气管扩张。1例中CT表现提示局灶性支气管病变，但该肺被误诊为无支气管扩张；支气管造影显示为柱状支气管扩张。1例中CT显示一个肺叶有柱状支气管扩张，而支气管造影显示正常，但该例支气管造影可能被误诊为假阴性。2例中肺部表现CT扫描比支气管造影显示得更好。结论是薄层CT是识别支气管扩张的准确方法。
