摘　　要：目的探讨32通道头颈联合相控阵线圈在颞颌关节盘移位的诊断价值。方法回顾性分析48例使用32通道头颈联合相控阵线圈检查的颞颌关节MRI,熟悉颞颌关节MRI的扫描方法,分析颞颌关节盘移位的MRI特征。结果48例颞颌关节MRI检查中,分别行双侧颞颌关节闭口斜矢状T1、压脂T2,冠状压脂T2以及双侧颞颌关节张口斜矢状T1、压脂T2,冠状压脂T2扫描。48例有35例阳性(72.9%),阴性13例(27.1%);35例中,单侧关节盘可复性前移位8例(22.9%),不可复性前移位9例(25.7%),一侧可复性、一侧不可复性前移位7例(20.0%),双侧关节盘可复性前移位5例(14.3%),不可复性前移位6例(17.1%);其中合并一侧关节盘内侧移位3例(8.6%)。结论32通道头颈联合相控阵线圈在颞颌关节MRI检查中,能发挥良好作用,对颞颌关节盘移位有很好的诊断价值,可以代替颞颌关节专用线圈应用于临床。Objective To investigate the diagnostic value of 32 channel head and neck combined phased front circle in temporomandibular disc displacement.Methods A retrospective analysis was performed on 48 cases of temporomandibular joint(TMJ)MRI examined by 32-channel head and neck combined with phased front circle.The MRI characteristics of TMJ disc displacement were analyzed.Results In 48 cases of TMJ MRI examination,bilateral TMJ closed mouth oblique sagittal T1,lipid pressure T2,coronal lipid pressure T2 and bilateral TMJ open mouth oblique sagittal T1,lipid pressure T2,coronal lipid pressure T2 scan were performed.Among the 48 cases,35(72.9%)were positive and 13(27.1%)were negative.Among the 35 cases,there were 8 cases(22.9%)of unilateral disc reversible anterior displacement,9 cases(25.7%)of irreversible anterior displacement,7 cases(20.0%)of unilateral disc reversible anterior displacement,5 cases(14.3%)of bilateral disc reversible anterior displacement,6 cases(17.1%)of irreversible anterior displacement.There were 3 cases(8.6%)with medial displacement of one articular disc.Conclusion The 32-channel head and neck combined phased front coil can play a good role in temporomandibular joint MRI examination,and has a good diagnostic value for temporomandibular joint disc displacement,it can be used in clinical practice instead of temporomandibular joint special coil.
