作者使用颅缝早闭的诊断来比较图像质量的主观评价与客观诊断效用。他们详细研究了一名观察者的反应，该观察者阅读了82名诊断为该疾病的患者的平片、计算机断层扫描（CT）扫描和CT扫描的三维重建（用三种不同方法获得）。观察者对每张图像的图像质量和诊断确定性进行评级。主观和客观的表现被认为是密切相关的。高质量的图像比低质量的图像更准确的诊断的基础。诊断性能的提高主要是由于特异性的提高，这一事实表明，在评价图像质量时，特异性和伴随的正常诊断是关注的焦点。
The authors used the diagnosis of craniosynostosis to compare subjective evaluation of image quality with objective diagnostic utility. They studied in detail the responses of one observer, who read plain radiographs, computed tomographic (CT) scans, and three-dimensional reconstructions of CT scans (obtained with three different methods) for 82 patients with this diagnosis. The observer rated image quality and certainty in diagnosis made from each image. Subjective and objective performances were found to be strongly linked. High-quality images served as the basis for more accurate diagnoses than low-quality images. The increase in diagnostic performance results primarily from increased specificity, a fact that suggests that specificity and the concomitant diagnosis of normalcy are the focus of attention when image quality is evaluated.
