ABSTRACT
PURPOSE:
To evaluate the value of fast field echo(FE) technique in accesing temporOmandibular joint(TMJ) dynamics. MATERIALS ANDMETHODS:
A series of 120 TMJ MRI examinations of 60 symptomatic patients was performed. The fast FE technique was used to provide dynamic images of the TMJs in various phase of mouth opening with a step-bite-block.RESULTS:
Among 120 cases, there were 30 cases which were normal, 21 cases of anterior displacement with reduction, 66 cases of anterior displacement without reduction, 11 cases of deformity of menisci, 23 cases of bony deformity, and 3 cases of medial displacement. The menisci and condyles were clearly delineated and the motions of the menisci during jaw opening were well evaluated in both normal and pathologic conditions.CONCLUSION:
The dynamic TMJ MRI scan using fast FE technique permits both fast scanning and study of joint dynamics as well as TMJ anatomy.
