The exquisite tissue contrast of MRI is optimal for visualizing the soft tissue and periarticular structures of the TMJ. Careful attention to technique with dedicated coils and high spatial resolution are essential. Dynamic maneuvers (opening and closing the mouth) are a necessary component of the examination to assess the position of the articular disk (which usually dislocates anteriorly). MRI is capable of demonstrating abnormalities of the disk, its supporting structures, synovium, and periarticular structures associated with internal derangement, degenerative and inflammatory arthropathies, and developmental and traumatic conditions.
