The chest roentgenogram is an accepted tool for the diagnosis of pneumonia. Little information is available, however, addressing the ability of physicians to distinguish bacterial from nonbacterial pneumonias by examination of the chest roentgenogram. Five different observers evaluated 36 chest films from patients with pneumonia who had a laboratory proven etiologic diagnosis. The sensitivity of roentgenogram diagnosis of bacterial pneumonia ranged from 42-58 percent. When clinical and laboratory data were provided to the observers the sensitivity ranged from 42-92 percent. This study indicates that chest film examination is too insensitive to be useful for the selection of patients who have bacterial pneumonia from those whose pneumonia is non-bacterial.
胸部X线照片是诊断肺炎的一种公认工具。然而，关于医生通过检查胸部X线照片来区分细菌性肺炎和非细菌性肺炎的能力，可获得的信息很少。五位不同的观察者评估了36例肺炎患者的胸部X光片，这些患者的病因诊断已通过实验室证实。胸部X光片诊断细菌性肺炎的敏感性在42%至58%之间。当向观察者提供临床和实验室数据时，敏感性在42%至92%之间。这项研究表明，胸部X光片检查的敏感性太低，无法用于区分细菌性肺炎患者和非细菌性肺炎患者。
