Abstract

Radiographic images can now be produced without the requirement of film processing and development, and can be displayed rapidly on a computer monitor. We assessed junior doctors' performance in interpreting images from 25 patients being investigated for possible fracture and also compared the diagnostic abilities of casualty officers with those of radiology specialist registrars. For interpretation of images viewed at a workstation or as filmed laser images, respectively, sensitivities were 75% and 78%, and specificities were 65% and 76%. These differences were not significant. There was a tendency for radiology specialist registrars to be less specific when reviewing images at a workstation. The demonstration that there is no loss in diagnostic quality when casualty officers interpret fracture images in a purely digitally acquired and viewed format forms a robust basis for economic evaluation of the technology.

摘要

现在无需进行胶片冲洗和显影就能生成X光影像，并且可以在电脑显示器上快速显示。我们评估了初级医生对25名疑似骨折患者影像的解读表现，还比较了急诊医生和放射科专科住院医生的诊断能力。对于分别在工作站查看的影像或胶片激光影像的解读，敏感度分别为75%和78%，特异度分别为65%和76%。这些差异并不显著。放射科专科住院医生在工作站查看影像时，特异度有降低的趋势。急诊医生以纯数字获取和查看的形式解读骨折影像时，诊断质量没有损失，这一结果为该技术的经济学评估提供了有力依据。
