慢性阻塞性肺病中X线和肺功能的关系

The Correlation of Measurement of Chest Film and Pulmonary Function Tests in COPD.

为评价COPD 中胸部X 线表现和肺功能的关系,对126例患者作了X 线胸片测量和肺功能检查之间统计学关系的研究。共测量了8项X 线征象,做了8项肺功能检查。结果发现4项X线测量与气道阻塞有显著相关意义;肺高,膈肌位置,右下肺动脉横径和左肋膈角度数。但它们在诊断有无气道阻塞上仍有不少假阴、阳性病例,它们的诊断指数是不高的。作者认为从COPD 患者的胸部X 线平片表现预测其肺功能是不完全可靠的。

To evaluate the correlation of radiographicappearance and pulmonary function tests,thestatistical correlations of pulmonary functiontests and measurements of chest film were madein 126COPD patients.Four meaurements weresignificant with airway obstruction:(1)thelung height,(2)the level of diaphragm,(3)the diameter of right inferior pulmonary arteryand(4)the degree of left costalphrenic sulcus.But there were a lot of false positive or falsenegative cases in the diagnosis of airway ob-struction.Their diagnosis indices were too low-er.The authors consider that in the individualpatiennt of COPD the pulmonary function can't reliably predicted from the measurements ofchest film.
