Mobile displays may have the ability to increase the flexibility of consulting radiologists if they can be shown not to negatively influence a reader's performance in clinical tasks. The authors report a comparison of a mobile display with a larger liquid crystal display for the task of making a binary decision for the diagnosis of tuberculosis on chest radiography. Deidentified DICOM images of 240 chest x-rays were transferred from a PACS to an iPad 2 running OsiriX HD software. The images were reviewed independently by 5 radiologists of varying experience and were graded as positive or negative for tuberculosis on both the liquid crystal display monitor and the iPad. The reading sessions were a minimum of 2 weeks apart to minimize recall bias. Agreement was measured in terms of κ statistics. Overall, multirater generalized κ was 0.9694. These results suggest that there is no detectable effect of monitor type (liquid crystal display or iPad 2) on the reader's decision for the task of tuberculosis diagnosis.
如果移动显示器不会对读者在临床任务中的表现产生负面影响，那么它们可能有能力提高放射科医生的灵活性。作者报告了一项比较研究，比较了移动显示器和更大的液晶显示器在胸部 X 光片上进行结核病诊断的二分类决策任务中的表现。将 240 张胸部 X 射线的去标识 DICOM 图像从 PACS 传输到运行 OsiriX HD 软件的 iPad 2 上。由 5 名经验不同的放射科医生独立对这些图像进行审查，并在液晶显示器和 iPad 上对结核病进行阳性或阴性分级。阅读会议至少相隔 2 周，以最大程度地减少回忆偏倚。以 κ 统计量衡量一致性。总体而言，多评分者广义 κ 为 0.9694。这些结果表明，显示器类型（液晶显示器或 iPad 2）对读者进行结核病诊断任务的决策没有可检测到的影响。
