放射科医生在解释传统和数字化图像获得不同的放射程序之间的差异是一个重要的研究问题，在这些时代的实施和增长的数字模式。作者进行了一项多观察者研究，以确定放射科医师阅读后前位常规X线片、激光打印到胶片上的数字化X线片以及高分辨率工作站（视频监视器）上显示的图像的性能。由7名放射科医生对300张图像进行评价，记录他们对存在或不存在以下一种或多种异常的顺序置信度：间质性疾病、结节和气胸。受试者操作特征分析显示，个体阅片者检测不同异常的差异具有统计学意义。当使用激光打印X线片或工作站而不是传统X线片时，整个组显示出观察者检测间质性疾病和气胸的性能显著降低。
The differences among radiologists in interpreting conventional and digitized images obtained with different radiologic procedures is an important research issue in these times of implementation and growth of the digital modalities. The authors performed a multiobserver study to determine the performance of radiologists reading posteroanterior conventional radiographs, digitized radiographs laser printed onto film, and images displayed on a high-resolution workstation (video monitor). A total of 300 images were evaluated by seven radiologists who recorded their ordinal confidence rating of the presence or absence of one or more of the following abnormalities: interstitial disease, nodule, and pneumothorax. Receiver operating characteristic analysis showed statistically significant differences for the detection of different abnormalities by individual readers. The group as a whole showed a significant reduction in observer performance for the detection of interstitial disease and pneumothorax when the laser-printed radiographs or the workstation was used rather than conventional radiographs.
