The initial chest radiographs of 31 patients with laboratory-proved pneumonia were evaluated by a panel of 6 radiologists who had no prior knowledge of the clinical data. No statistical reliability was found for distinguishing bacterial from nonbacterial pneumonia. Radiographic diagnoses were 67% accurate for the 16 cases of bacterial pneumonia, and 65% accurate for the 9 viral cases. Six cases of Mycoplasma pneumonia were diagnosed as nonbacterial 19% of the time, and as "bacterial pneumonia" 81% of the time.
31例经实验室确诊为肺炎的患者的初始胸部X光片由6名对临床数据一无所知的放射科医生组成的小组进行评估。在区分细菌性肺炎和非细菌性肺炎方面未发现统计学可靠性。对于16例细菌性肺炎病例，影像学诊断的准确率为67%，对于9例病毒性肺炎病例，准确率为65%。6例支原体肺炎病例在19%的时间里被诊断为非细菌性肺炎，在81%的时间里被诊断为“细菌性肺炎”。
