Three imaging modalities were compared for diagnostic efficacy in the detection of simulated osteoarthritic lesions created by a series of dentin chips placed at four locations on the head of a temporomandibular joint condyle in a dry human skull. The modalities included panoramic-based biplanar temporomandibular joint views, parasagittal linear zonography, and sagittal-view, computer-controlled, multidirectional tomography. Equal numbers of images with and without chips were viewed by six examiners. Observers recorded the presence or absence of lesions on a 100-point confidence scale. Responses were used to construct ROC curves. Pooled data sorted by modality produced areas under the curves of 0.7421 (zonography), 0.6627 (panoramic imaging), and 0.7478 (tomography). No statistically significant difference in lesion detection was found among the three modalities, between observers, or within observers.
在一个干燥的人类头骨上，将一系列牙本质碎片放置在颞下颌关节髁突头部的四个位置，模拟骨关节炎病变，比较了三种成像方式对其的诊断效能。这些成像方式包括基于全景的双平面颞下颌关节视图、矢状旁线性体层摄影术以及矢状视图、计算机控制的多向断层扫描。六名检查人员查看了数量相等的有碎片和无碎片的图像。观察者以100分的置信度量表记录病变的有无。这些反应被用于构建ROC曲线。按成像方式分类的汇总数据得出曲线下面积分别为0.7421（体层摄影术）、0.6627（全景成像）和0.7478（断层扫描）。在三种成像方式之间、观察者之间或观察者内部，在病变检测方面均未发现统计学上的显著差异。
