We examined the potential of the iPad 2 as a teleradiologic tool for evaluating brain computed tomography (CT) with subtle hemorrhage in the conventional lighting conditions which are common situations in the remote CT reading. The comparison of the clinician's performance was undertaken through detecting hemorrhage by the iPad 2 and the clinical liquid crystal display (LCD) monitor. We selected 100 brain CT exams performed for head trauma or headache. Fifty had subtle radiological signs of intracranial hemorrhage (ICH), while the other 50 showed no significant abnormality. Five emergency medicine physicians reviewed these brain CT scans using the iPad 2 and the LCD monitor, scoring the probability of ICH on each exam on a five-point scale. Result showed high sensitivities and specificities in both devices. We generated receiver operating characteristic curves and calculated the average area under the curve of the iPad 2 and the LCD (0.935 and 0.900). Using the iPad 2 and reliable internet connectivity, clinicians can provide remote evaluation of brain CT with subtle hemorrhage under suboptimal viewing condition. Considering the distinct advantages of the iPad 2, the popular out-of-hospital use of mobile CT teleradiology would be anticipated soon.
我们研究了 iPad 2 作为一种远程 CT 阅读中常见的暗室条件下评估脑 CT 细微出血的远程放射学工具的潜力。通过使用 iPad 2 和临床液晶显示器 (LCD) 监测器检测出血来比较临床医生的表现。我们选择了 100 例因头部外伤或头痛而行脑 CT 检查的患者。其中 50 例有颅内出血 (ICH) 的细微影像学征象，而另外 50 例无明显异常。5 名急诊医师使用 iPad 2 和 LCD 监视器对这些脑 CT 扫描进行了回顾，并对每个检查的 ICH 可能性进行了五分制评分。结果表明两种设备的敏感性和特异性都很高。我们生成了受试者工作特征曲线，并计算了 iPad 2 和 LCD 的平均曲线下面积 (0.935 和 0.900)。使用 iPad 2 和可靠的互联网连接，临床医生可以在次优的观察条件下提供脑 CT 细微出血的远程评估。考虑到 iPad 2 的明显优势，预计移动 CT 远程放射学的院外广泛应用将很快实现。
