To evaluate the diagnostic possibilities of Digital Radiography (DR) and of Conventional Radiography (CR) in the diagnosis of fine chest lesions, 100 patients with AIDS were examined with both techniques. The gold standards were 67Ga scintigraphy and bronchial washing in 100 patients and Computed Tomography (CT) in 50 patients. The data obtained from DR and CR examinations were separately evaluated by 4 readers and subsequently analyzed by ROC curves with Standard Error calculation and by comparing the areas below the characteristic curves with Student's paired t-test (p less than or equal to 0.05). Statistical analysis showed DR and CR to be of equivalent diagnostic value in the study of interstitial lung diseases.
为评估数字X线摄影（DR）和传统X线摄影（CR）在诊断肺部细微病变中的诊断可能性，对100例艾滋病患者采用这两种技术进行了检查。100例患者的金标准是67Ga闪烁扫描和支气管灌洗，50例患者的金标准是计算机断层扫描（CT）。由4名阅片者分别评估从DR和CR检查获得的数据，随后通过计算标准误差的ROC曲线并使用学生配对t检验（p≤0.05）比较特征曲线下的面积进行分析。统计分析表明，在间质性肺疾病的研究中，DR和CR具有同等的诊断价值。
