The diagnostic process in sialography was evaluated using the mouse parotid gland as a model. The relative significance of each of the three diagnostic phases, psychophysical, psychological and nosological, was determined by analysing observer accuracy in detecting sialoadenitis and sialodochitis on digital and analogue microsialograms. Automated diagnosis based on parametric values of the digitized image was compared with the human system using ROC analysis. The overall accuracy of automated diagnosis was superior to that of an observer with analogue images. It is concluded that if observers were to be given the same quantitative information and informed of its diagnostic value in the psychological phase, then variation in the detection of the abnormalities could be reduced and the overall diagnostic accuracy in sialography improved.
以小鼠腮腺为模型评估了涎腺造影的诊断过程。通过分析观察者在数字和模拟涎腺造影片上检测涎腺炎和涎管炎的准确性，确定了心理物理学、心理学和疾病分类学这三个诊断阶段各自的相对重要性。使用ROC分析将基于数字化图像参数值的自动诊断与人工系统进行了比较。自动诊断的总体准确性优于使用模拟图像的观察者。得出的结论是，如果在心理学阶段为观察者提供相同的定量信息并告知其诊断价值，那么可以减少异常检测中的差异并提高涎腺造影的总体诊断准确性。
