| Outline of Final Research Achievements |
The purpose of this study was to develop quantitative evaluation methods for the inferior alveolar nerve and masticatory muscles by using functional MR imaging including diffusion tensor MRI (DTI). The study was performed with the approval of the ethics committee of our institution. The major results were as follows: 1) According to the DTI study applied to the inferior alveolar nerve of normal healthy subjects, normal ranges of FA and ADC values of the nerve were clarified. Further, the nerve fibers were directly visualized by tractography in 76% of the cases. 2) According to the IVIM analysis applied to the lateral pterygoid muscles of patients with TMD, it was clarified that the increase of f value was greater in the superior belly than the inferior belly.
