寰枢关节脱位的比较影像学诊断价值

Clinical value of imaging examination in diagnosing atlantoaxial dislocation

目的 :比较寰枢关节影像学检查方法的优缺点,评价各种影像学检查在寰枢关节脱位中的临床诊断价值。方法:选取某院77例经临床综合确诊寰枢关节脱位的患者,均行CT三维重建,其中45例行X线检查,26例行磁共振成像(magnetic resonance imaging,MRI)检查。观察寰枢关节脱位的影像学表现,分析其临床价值及特点。结果:CT三维重建77例,阳性诊断77例(阳性率100.0%);X线检查45例,阳性诊断29例(阳性率64.44%);MRI检查26例,阳性诊断17例(阳性率65.38%)。结论:目前影像学检查仍是诊断寰枢关节脱位的最主要方法,临床上具有确定性诊断价值,其中CT三维重建显示脱位征象最清楚、直观。

Objective To explore the features and clinical values of imaging examinations for atlantoaxial dislocation.Methods Totally 77 patients with atlantoaxial dislocation underwent 3D CT reconstruction, and then 45 ones went through X-ray examination and 26 ones went through MRI examination. The manifestations of atlantoaxial dislocation were observed, and the features and clinical values of X-ray and MRI examinations were analyzed. Results CT examination found 77 cases of atlantoaxial dislocation with the positive rate of 100%, X-ray examination found 29 cases from 45 ones with the positive rate of 64.44% and MRI examination found 17 cases from 26 ones with the positive rate of65.38%. Conclusion Imaging examination, especially CT examination, are still the main method for diagnosing atlantoaxial dislocation.
