Abstract:
The authors introduced flip back spin echo (FBSE) technique for MR imaging of the temporomandibular joint (TMJ) instead of conventional spin echo (SE) technique, and evaluated whether FBSE technique in MRI of TMJ is adequate for the diagnosis of the disorders or not. FBSE T1 parasagittal images in closed mouth state and sequential opening and closing mouth states using patient's own finger(s) were obtained and then FBSE T1 paracoronal image in closed mouth state and STAGE(short tip angle gradient echo) parasagittal T2WI were followed. All 30 images of the symptomatic TMJs using FBSE technique were excellent in the visualization of articular and their displacement, and we could easily diagnose the internal derangement. FBSE technique was adequate for the diagnosis of internal derangement of the TMJ, and the modified cine display from images using FBSE technique was advantageous in the diagnosis of the disorders by visualization of the dynamic motion of the TMJ.
