The most frequent intracapsular disorders of the TM joint are disorders of the complex of the articular head and disc, i.e. a discopathy of the mandibular joint. To express intracapsular problems more accurately and to select correctly the therapeutic procedure it is important to visualize reliably the articular disc. To this end various imaging methods were introduced or modified (arthrography, computed tomography). Imaging by magnetic resonance is better than other imaging methods in many parameters. During the period from 1994–1997 the authors examined by magnetic resonance 30 mandibular joints. The joints were examined by T1 and T2 with weighted SE sequencies with the mouth closed and open and subsequently by pseudo-dynamic imaging, i.e. special GE sequence. The authors recommend a combination of the two methods of MR imaging in the diagnosis of intracapsular disorders of the mandibular joint.
