| Research Abstract |
Trajectory and velocity patterns based on 3.0 T pseudodynamic MRI identified the affected side and determined the extent of morbidity in the Cd as well as the Da and Dp. The typical abnormal movement pattern of discs with anterior displacement (with and without reduction) and pathological structural changes of the articular disc (such as adhesion and perforation) could be identified. Grading of Da and Dp obscurity based on how well the areas were defined in the images, identifying the condylar positions in relation to the glenoid fossa and articular eminences, and observing the changes in Dp contour types at opening were useful for diagnosing TMJ abnormalities. Results obtained by SR-CAD system were superior to results obtained by the Naive Bayes system and the Bayesian network system. In cases of 3.0T TMJ MRI, bone changes and disc displacement were diagnosed with efficiency of 100%.
