説明
This investigation evaluated the quality of coronal magnetic resonance images of the TMJ by altering the direction of scanning. Materials and methods: Coronal MR images of 158 TMJs were obtained at 0.2 Tesla (MRP-20 HITACHI MEDICO, Tokyo). MR imaging was performed on two coronal planes. The first plane was parallel to the posterior surface of the ramus of 81 TMJs. The second plane was perpendicular to the posterior slope of the eminence of 77 TMJs. Both coronas planes were parallel to the long axis of the condyle. Special attention was directed toward the clarity of the disc relative to the osseous anatomy. Results: Sixty-seven of 77 (87%) discs were well-defined using planes perpendicular to the posterior slope of the eminence. Using the other planes, 28 of 81 (35%) disc were well-defined. Conclusion: Coronal MR images obtained perpendicular to the posterior slope of the eminence demonstrated the anatomy of the disc better than coronal images obtained parallel to the posterior surface of the ramus.
