“…In a previous study comparing cadaver specimens with anatomical findings, MRI showed high sensitivity (87%), specificity (100%) and accuracy (93%) for TMJ bone abnormalities 24 . Moreover, in Kunihiko et al's clinical study on patients with TMD, the sensitivity, specificity and accuracy of 3.0‐T MRI for detecting condylar bone abnormalities was high compared with CBCT (100%, 73%, and 88%, respectively) 25 . The findings of these two studies are partially consistent with our results.…”

Temporomandibular disorders (TMDs) are the most common cause of orofacial pain, with an incidence of 15% in the general adult population. 1 Temporomandibular disorders mainly affect the soft and hard tissues of the temporomandibular joint (TMJ) and the masticatory muscles. 2 Degenerative joint disease (DJD) of the TMJ is an important type of TMD characterised by joint sounds (coarse or fine crepitus), pain in the joints and muscles and joint movementrestriction. 3-5 Degenerative joint disease can critically affect an individual's health-related quality of life. 6 According to the latest diagnostic criteria for TMD (DC/TMD), 2 the following computed tomography (CT) or cone-beam CT (CBCT) imaging findings are necessary to establish a diagnosis of DJD: condylar erosion, osteophyte formation, extensive condylar sclerosis, and/or subcortical cystic degeneration.

“…The cartilage layer was not visible even with high-field 7T MR microimaging. Currently, in clinical practice, 3T MR imaging is used as high-power field equipment, however, detecting pathological changes on the level of the cartilage of the mandibular condyle is difficult, with the exception of large cartilage masses, such as in osteochondromatosis (12,13).…”

Background/Aim: Few studies have performed magnetic resonance (MR) imaging on live animals. The aim of this study was to perform 7T MR microimaging of the temporomandibular joint (TMJ) multiple times in the same living mice with malocclusion, and to compare between MR imaging and histopathological findings. Materials and Methods: Mice were examined by MR imaging at 3-4, 6 and 12 weeks following the attachment of a metal tube on the left mandibular incisor. Histopathological examination was done at 3, 6 and 12 weeks. Results: The detailed structure of the TMJ was evident from MR microimaging. The histopathological examination showed some changes in the cartilage, but no changes in the bone structure of these mice. Conclusion: We successfully performed multiple 7T MR imaging in living mice. Even if the TMJ showed no obvious changes on MR images, minute changes may be present in the cartilage.

“…The status of the retrodiscal tissue, attached muscles, and overall inflammation are also assessed. New advances have made it possible to provide a thorough assessment of the bony and cartilaginous structures in the joint, which could make (cone beam) computed tomography ((CB)CT) evaluations theoretically obsolete in the future 8,9 .…”

The aim of this retrospective observational study was to assess the potential agreement between independent magnetic resonance imaging (MRI) and arthroscopic findings and their respective contributions to a final diagnosis in patients with refractory temporomandibular joint disorders. Two dentomaxillofacial radiologists and two oral and maxillofacial surgeons scored 50 joints. All observers, who were blinded to additional clinical information, used a specific scoring form and selected one or more diagnostic labels. Agreement between MRI and arthroscopy and their contributions to the final diagnosis were assessed as primary outcomes using Fleiss' kappa. Intra-modality agreement and the correlation between signal intensity ratio (SIR) measurements on MRI and synovitis grading on arthroscopy were assessed as secondary outcomes. Agreement between MRI and arthroscopy was poor. A fair level of agreement was only reached for reduction capacity of the disc and disc perforation. Arthroscopic diagnostic labels matched better with the final diagnosis, suggesting a bigger contribution to that diagnosis. Higher SIR measurements correlated with higher synovitis grading scores for the retrodiscal tissue and the posterior band of the disc. Intra-modality agreement was better in arthroscopy. When blinded to clinical information, arthroscopy and MRI observations can lead to different conclusions. The diagnostic outcomes of both examinations should be considered and integrated into a final diagnosis.
