Describe e role of MR imaging in e assessment of tem-poromandibular joint dysfunction, wi special emphasis on indirect signs of dys-function. Discuss e corre-lation between e MR imaging features and clinical symp-toms of temporo-mandibular joint dys-function. Xavier Tomas, MD Jaume Pomes, MD Juan Berenguer, MD Llorenc¸. MRI is e standard me od of evaluation of TMJ. e study should include oblique sagittal spin and gradient echo T2 WIs on each TMJ arately bo in open and closed mou positions. Some institutes use PD instead of spin echo T2 sequence. MR imaging allows detailed evaluation of temporomandibular (TMJ) anatomy because of its inherent tissue contrast and high resolution. Joint biomechanics can be assessed rough imaging patients in e closed and open jaw positions. Despite e accuracy of MR imaging in detecting disc position, results must be interpreted toge er wi clinical findings, because an anteriorly displaced. Plan e coronal oblique slices on e sagittal plane. angle e position block parallel to e sacrum. Check e positioning block in e o er two planes. An appropriate angle must be given in e axial plane (parallel to e sacral ala). Slices must be sufficient to cover e whole sacroiliac joints. To determine e value of MRI in temporomandibular joint (TMJ) disorders, e data of MRI-proven anterior disc dislocation wi out reduction (ADWOR) were correlated wi clinical history. 13, · Patient position when taking TMJ joint is ERECT or SUPINE.
