[Adding to the diagnostic possibilities of MR tomography of the TMJ]

54 patients with arthrogenous dysfunctions were examined by means of MR tomography. Imaging of the position and shape of the intraarticular soft tissues was achieved in 64 out of the 67 TMJs examined. The results give rise to the expectation that MR tomography can be further developed to provide a reliable diagnostic tool not only for detecting dislocations in the sagittal plane, but also for imaging mediolateral alterations in the disk position, disk perforations and restrictions in the physiologic mobility of the articular disk.
