Objective: The purpose of the study was to compare high-resolution ultrasonography (HR-USG) with magnetic resonance imaging (MRI) in the diagnosis of temporomandibular joint (TMJ) internal derangements. Materials and Methods: The study was conducted on 11 subjects with a chief complaint of TMJ discomfort, who were diagnosed as having TMJ internal derangement according to clinical diagnostic criteria (CDC) for temporomandibular disorders (TMD). A control group of eight subjects who had no sign of TMJ internal derangement were also examined. Imaging modalities (MRI and HR-USG) were performed on all the subjects (cases and controls). Results: Strong agreement was found between MRI and HR-USG in the diagnosis of TMJ internal derangements (k = 0.918, P < 0.001). Conclusion: MRI and HR-USG can be used to define the disc and its displacement.
