Measurements on standard frontal and lateral radiographs that reliably predict the presence or absence of chronic obstructive lung disease would be useful to the clinical radiologist when no other clinical data are available. Therefore, statistical correlations of pulmonary function tests and measurements of chest films were made in 104 men chosen from 1000 cases referred for pulmonary function tests in whom no obvious abnormality was present on the chest film. Two measurements were significantly correlated (p less than 0.001) without requiring correction for body surface area: (1) The height of the arc of the right diaphragm in the lateral projection. When 2.6 cm or less it identifies 67.7% of all patients with abnormal pulmonary function tests and 78.3% of patients with moderately or severely abnormal pulmonary function tests. (2) The height of the right lung in the posteroanterior projection. When this is 29.9 cm or more it will identify 69.8% of all patients with abnormal pulmonary function tests and 79.7% of patients with moderately to severely abnormal pulmonary function tests. These simple measurements will assist the radiologist to judge from standard chest radiographs whether a patient may or may not have chronic obstructive lung disease.
在没有其他临床数据可用时，能可靠预测慢性阻塞性肺疾病是否存在的标准正位和侧位X线片测量值，对临床放射科医生会很有用。因此，对从1000例因肺功能测试前来就诊且胸片无明显异常的病例中选取的104名男性进行了肺功能测试与胸片测量值的统计相关性分析。有两项测量值具有显著相关性（p小于0.001），且无需对体表面积进行校正：（1）侧位投照时右膈顶弧线的高度。当该高度为2.6厘米或更低时，可识别出所有肺功能测试异常患者中的67.7%以及中度或重度肺功能测试异常患者中的78.3%。（2）后前位投照时右肺的高度。当该高度为29.9厘米或更高时，可识别出所有肺功能测试异常患者中的69.8%以及中度至重度肺功能测试异常患者中的79.7%。这些简单的测量值将帮助放射科医生从标准胸片判断患者是否可能患有慢性阻塞性肺疾病。
