The recent advances in imaging of the temporomandibular joint (TMJ), especially the introduction of MR imaging and surface colls allowing precise visualization of superficial structures led us to reconsider the different techniques used in this very complex anatomical region, due to both its morphology and function. We also tried to determine their respective role, especially in the study of TMJ dysfunction syndromes, that represent the most frequent pathology of this region. Conventional radiography allows us to appreciate the overall amplitude of the joint movements, and to study bone abnormalities, but CT is much more precise in the study of cortical bone. In TMJ dysfunction, the joint itself is studied by either arthrography or MRI, but both techniques have their limitations and remain complementary in some aspects, which are detailed here, so that the choice between them depends on availability and therapeutic indications.
颞下颌关节（TMJ）成像的最新进展，尤其是磁共振成像（MR imaging）和表面线圈的引入，使得能够精确显示浅表结构，这让我们重新审视了在这个解剖结构和功能都非常复杂的区域所使用的不同技术。我们还试图确定它们各自的作用，特别是在颞下颌关节功能障碍综合征的研究中，该综合征是该区域最常见的病理情况。传统放射摄影使我们能够了解关节运动的整体幅度，并研究骨质异常，但计算机断层扫描（CT）在皮质骨研究方面更为精确。在颞下颌关节功能障碍中，关节本身可通过关节造影或磁共振成像进行研究，但这两种技术都有其局限性，并且在某些方面仍具有互补性，本文将对此进行详细阐述，因此在它们之间的选择取决于可用性和治疗指征。
