In marked chronic obstructive pulmonary emphysema, especially in the classical emphysematous type of abnormal thorax, a good correlation can be found between the anteroposterior expansion of the thorax, the reduced inspiratory capacity, the clinical state, disturbed mechanics of breathing and the x-ray-state. On the contrary, in clinical emphysema of a lower degree, especially in subclinical, i. e. in predominantly asymptomatic pulmonary emphysema of the elderly, the effectiveness of the roentgenological examination is very small.
在明显的慢性阻塞性肺气肿中，尤其是在典型的气肿型胸廓异常中，胸廓的前后径扩大、吸气能力降低、临床症状、呼吸力学紊乱与X线表现之间存在良好的相关性。相反，在程度较轻的临床肺气肿中，尤其是在亚临床状态，即老年人以无症状为主的肺气肿中，X线检查的有效性非常小。
