This study compared the accuracy of two noninvasive methods, computerized axiography and magnetic resonance tomography (MRT), in diagnosing temporomandibular joint (TMJ) disorders. Forty-seven subjects underwent axiography and subsequent assessment of the TMJ by MRT. The statistical analysis referred to the correlations of the most relevant clinical diagnoses, i.e., no appreciable disease, disk displacement with reposition, disk displacement without reposition, morphologic alterations, and hypermobility of the condyle. In 70% of the disk-displacement-with-reposition and disk-displacement-without-reposition patient groups, axiography and MRT gave the same information. In other patient groups, the axiography findings agreed with the MRT findings in 45% of the cases. It was concluded that although a large percentage of morphologic alterations could be detected by MRT, axiography determined the dysfunctional dynamics more clearly.
本研究比较了两种非侵入性方法——计算机轴性断层摄影术和磁共振断层扫描（MRT）在诊断颞下颌关节（TMJ）紊乱方面的准确性。47名受试者接受了轴性断层摄影术检查，随后通过MRT对TMJ进行评估。统计分析涉及最相关的临床诊断的相关性，即无明显疾病、可复性盘移位、不可复性盘移位、形态改变和髁突活动度过大。在70%的可复性盘移位和不可复性盘移位患者组中，轴性断层摄影术和MRT给出了相同的信息。在其他患者组中，轴性断层摄影术的结果在45%的病例中与MRT的结果一致。得出的结论是，虽然MRT可以检测到很大比例的形态改变，但轴性断层摄影术能更清楚地确定功能障碍的动态情况。
