OBJECTIVE:To evaluate the evidence for the efficacy of magnetic resonance imaging (MRI) in the diagnosis of disk position and configuration, disk perforation, joint effusion, and osseous and bone marrow changes in the temporomandibular joint. STUDY DESIGN:A PubMed literature search with specific indexing terms and a hand search were made. Two reviewers assessed the level of evidence of relevant publications as high, moderate, or low. Based on this, the evidence grade for diagnostic efficacy was rated as strong, moderately strong, limited, or insufficient. RESULTS:The literature search yielded 494 titles, of which 22 were relevant. No publication had a high level of evidence, and 12 had moderate and 10 low levels of evidence. The evidence grade for diagnostic efficacy expressed as sensitivity, specificity, and predictive values was insufficient. CONCLUSION:That evidence is insufficient emphasizes the need for high-quality studies on the diagnostic efficacy of MRI, incorporating accepted methodologic criteria.

目的:评估磁共振成像(MRI)在诊断椎间盘位置和结构,椎间盘穿孔,关节积液以及颞下颌关节骨和骨髓变化方面的有效性的证据。
研究设计:进行了PubMed文献检索,包括特定的索引词和人工检索。两名审稿人对相关出版物的证据水平进行了评估,等级为高,中或低。基于此,诊断功效的证据等级被评为强,中度强,有限或不足。
结果:文献检索产生494种图书,其中22种具有相关性。没有出版物有高水平的证据,有12个有中度证据,有10个低水平证据。以敏感性,特异性和预测值表示的诊断功效的证据等级不足。
结论:证据不足,强调需要结合公认的方法学标准对MRI的诊断功效进行高质量的研究。
