【摘要】 目的介绍CT双对比领下颌关节造影技术，并评价其在颞下颌关节功能紊乱综合征中的诊断价值。方法对14例常规关节造影诊断困难的病例，进行CT双对比颞下颌关节造影检查。结果14例患者经CT双对比造影检查为正常考1例，可复性盘前移位者1例，不可复性盘前移位老2例，关节盘穿孔2例，关节盘粘连8例。结论CT双对比颞下颌关节造影术是常规关节造影的重要补充，对关节盘粘连有特殊的诊断价值。更多还原

【Abstract】 Objective To introduce double-contrast arthrography of TMJ with reformatted sagittal and coronal CT imaging and to evaluate the value of its application in the diagnosis of temporomandibular joint dysfunction. Methods 14 patients in whom diagnosis can not be established with conventional arthrography were examined by double-contrast arthrography with reformatted sagittal and coronal CT imaging. Results In double-contrast arthrography with CT imaging. 1 case was normal, 1 case had anterior displacement with reduction; 2 cases were anterior displacement without reduction, and 8 cases were with disk adhesion. Conclusion The double-contrast arthrography with re formatted sagittal and coronal CT imaging was a very important alternative to conventional arthrography, and has special value to demonstrate adhesion of TMJ.更多还原
