【摘要】 目的:探讨颞下颌关节紊乱病(temporomandibular joint dysfunction,TMD)的MRI动态电影扫描表现及其诊断价值。方法:回顾性分析30例临床诊断为颞下颌关节紊乱病的MRI动态电影扫描表现。结果:30例32侧有症状的关节中,22侧髁突活动度过小,其中6侧伴关节盘前移位,4侧伴髁突骨质增生,另有2侧仅见关节盘前移,但关节动度尚可,8侧未见异常,动态电影MRI能清楚观察到颞下颌关节的动度、关节盘移位的情况以及髁盘关系。结论:MRI动态电影扫描技术对颞下颌关节紊乱病的早期诊断具有很高的价值。更多还原

【Abstract】 Objective: To evaluate MRI dynamic movie scan technique in diagnosing temporomandibular joint dysfunction (TMD) . Methods: Dynamic movie scan MRI findings in 30 cases (32 symptomatic joints ) with TMD were retrospectively analyzed. Results: 8 joints had displacement of the disk, 22 joints condyles showed a decrease in motion range and 4 joints condyles showed hyperostosis osteosclerosis. Conclusion: MRI dynamic movie scan technique plays a very important role in the early diagnosis of TMD.更多还原
