To evaluate the value of X-ray and spiral computed tomography (SCT) in the diagnosis of Swyer-James syndrome (SJS).
A total of 28 patients, 12 males and 16 females, were studied retrospectively. Ages ranged from 11 to 57 years, the mean age was 32 years. All patients underwent inspiratory chest X-ray films, 5 with expiratory chest films and 1 with bronchogram. Furthermore, inspiratory and expiratory SCT scans were performed. The SCT findings were analyzed and compared with X-ray films.
SCT demonstrated 56 lobes with hyperlucency and diminished vascularity. The size of 51 lobes were smaller and 5 were normal. X-ray films showed that hyperlucency was only in 29 lobes, in which 19 lobes were small-sized and the other 10 lobes normal. There were 56 lobes with air-trapping on expiratory SCT scans, but only 5 lobes with air-trapping on expiratory X-ray films. Bronchogram in 1 case demonstrated bronchiectasis and bronchiolitis obliterans. SCT showed 24 patients with bronchiectasis, 9 patients with tuberculosis, 10 patients with bronchiolitis, and 2 with segmental collapse.
SCT scan is superior to chest radiography in the diagnosis and differential diagnosis of SJS.
评估X线及螺旋计算机断层扫描（SCT）在Swyer-James综合征（SJS）诊断中的价值。
回顾性研究28例患者，其中男性12例，女性16例。年龄11至57岁，平均年龄32岁。所有患者均进行了吸气位胸部X线片检查，5例进行了呼气位胸部X线片检查，1例进行了支气管造影。此外，还进行了吸气和呼气SCT扫描。分析SCT表现并与X线片进行比较。
SCT显示56个肺叶透亮度增加且血管减少。51个肺叶体积较小，5个正常。X线片显示仅29个肺叶透亮度增加，其中19个肺叶体积小，另10个正常。呼气期SCT扫描发现56个肺叶有空气潴留，而呼气期X线片仅发现5个肺叶有空气潴留。1例支气管造影显示支气管扩张和闭塞性细支气管炎。SCT显示24例患者有支气管扩张，9例有肺结核，10例有细支气管炎，2例有节段性肺不张。
SCT扫描在SJS的诊断和鉴别诊断方面优于胸部X线检查。
