Pulmonary function tests (diffusing capacity for carbon monoxide of the lungs) and radiological imaging (plain chest film, high resolution computed tomography (CT) and CT expiratory density mask) were compared in the assessment of 29 patients with suspected airways obstruction. Conventional roentgenogram showed a good agreement with the diffusing capacity of the lungs and proved to be useful in predicting the presence of severe emphysema, but the extension of the disease was more precisely assessed by computed tomography. A good agreement was found between high resolution CT and density mask CT, although the "subjective" high resolution identified more patients with mild emphysema than the "automated" density mask. In conclusion, although the plain chest film is useful in the diagnosis of severe emphysema, CT (especially when high resolution is used) is helpful in identifying cases of mild disease and in diagnosing the type of emphysema.
对29例疑似气道阻塞患者进行评估时，比较了肺功能测试（肺一氧化碳弥散量）和放射影像学检查（胸部平片、高分辨率计算机断层扫描（CT）及CT呼气密度掩膜）。传统X线片显示与肺弥散量有良好的一致性，且被证明有助于预测严重肺气肿的存在，但计算机断层扫描能更精确地评估疾病的范围。高分辨率CT与密度掩膜CT之间存在良好的一致性，尽管“主观”的高分辨率CT比“自动”的密度掩膜CT识别出更多轻度肺气肿患者。总之，虽然胸部平片对严重肺气肿的诊断有用，但CT（尤其是使用高分辨率时）有助于识别轻度病例并诊断肺气肿的类型。
