顎関節内障における関節造影とMRI併用の検討

抄録

We correlated the arthrographic findings of the interior joint space with the magnetic resonance imaging in 3 patients of anterior displacement of the meniscus with reduction and 6 patients without reducnon.
Displacement of the meniscus was demonstrated by arthrography and MRI. Deformity of the meniscus was better revealed by MRI, but not by arthrography. Perforation or fibrous adhesion of the meniscus was not shown by MRI.
Because it is difficult to diagnose a soft tissue derangement of the TMJ based on clinical symptoms, arthrography and NIRI Firlp to accurately diagnose in internal derangement of the TMJ.
