Bronchopulmonary dysplasia, first described by Northway in 1967 as a separate entity, was graded into four stages. Basing on thoracic x-ray films of 14 newborn and prematurely born infants an attempt has been made to analyse the x-ray patterns of signs characterising bronchopulmonary dysplasia and to establish a relation between the x-ray signs and the four stages. With few exceptions the various radiologic signs were seen in all stages, although with varying incidence. It follows that x-ray visualisation of the thorax yields limited pointers only to the actual stage of the disease. Roentgenography is the method of choice (in connection with the pattern of clinical signs) for diagnosing bronchopulmonary dysplasia and should be also employed for controlling the course of the disease and for the identification of eventual complications.
支气管肺发育不良于1967年由诺斯韦首次作为一个独立的疾病实体进行描述，并分为四个阶段。基于14名新生儿和早产儿的胸部X光片，试图分析表征支气管肺发育不良的体征的X光模式，并建立X光体征与四个阶段之间的关系。除少数例外，各个放射学体征在所有阶段均可见，尽管发生率有所不同。由此可见，胸部X光检查对疾病的实际阶段仅提供有限的指示。X线摄影是诊断支气管肺发育不良的首选方法（结合临床体征模式），也应用于监测疾病进程和识别可能的并发症。
