摘要

目的:在西南亚和阿富汗的尘土飞扬、艰苦的环境中进行军事部署与哮喘和细支气管炎等症状性呼吸道疾病有关。胸部高分辨率计算机断层扫描(HRCT)成像在该人群肺部疾病诊断中的作用尚不清楚。与健康对照组相比,我们研究了HRCT的视觉评估,以识别部署相关的肺部疾病。材料和方法:由3名独立的胸部放射科医生对46名健康对照和45名有症状的军事部署人员的胸部HRCT图像进行评分,这些人员患有临床确诊的哮喘和/或活检确诊的远端肺部疾病。我们使用χ2、Fisher精确或t检验以及逻辑回归(如适用),比较了部署者和对照者之间、哮喘部署者和活检证实的远端肺部疾病部署者之间的人口统计学和临床特征以及成像发现频率。我们还分析了评分者对影像学结果的一致性。结果:与对照组相比,呼气性空气滞留是唯一一个在部署人员中明显更频繁的胸部CT成像发现。24名经活检证实为细支气管炎和/或肉芽肿性肺炎的部署人员中,没有一人的HRCT表现为吸气马赛克减弱或小叶中心结节。在21例经活检证实为肺气肿的退伍军人中,只有2例在HRCT上有肺气肿。

Findings on High Resolution Computed Tomography in Symptomatic Veterans with Deployment-Related Lung Disease.

Purpose: Military deployment to dusty, austere environments in Southwest Asia and Afghanistan is associated with symptomatic airways diseases including asthma and bronchiolitis. The utility of chest high-resolution computed tomographic (HRCT) imaging in lung disease diagnosis in this population is poorly understood. We investigated visual assessment of HRCT for identifying deployment-related lung disease compared with healthy controls.

Materials and methods: Chest HRCT images from 46 healthy controls and 45 symptomatic deployed military personnel with clinically confirmed asthma and/or biopsy-confirmed distal lung disease were scored by 3 independent thoracic radiologists. We compared demographic and clinical characteristics and frequency of imaging findings between deployers and controls, and between deployers with asthma and those with biopsy-confirmed distal lung disease, using χ2, Fisher exact or t tests, and logistic regression where appropriate. We also analyzed inter-rater agreement for imaging findings.

Results: Expiratory air trapping was the only chest CT imaging finding that was significantly more frequent in deployers compared with controls. None of the 24 deployers with biopsy-confirmed bronchiolitis and/or granulomatous pneumonitis had HRCT findings of inspiratory mosaic attenuation or centrilobular nodularity. Only 2 of 21 with biopsy-proven emphysema had emphysema on HRCT.

Conclusions: Compared with surgical lung biopsy, visual assessment of HRCT showed few abnormalities in this small cohort of previously deployed symptomatic veterans with normal or near-normal spirometry.
