摘要
目的比较颞下颌关节盘粘连的磁共振(MRI)和CT双对比造影结果,探讨它们在关节盘粘连中的诊断价值。方法对18例颞下颌关节关节盘粘连病例的MRI和CT双对比造影结果进行比较分析,分析内容包括粘连的部位、程度、是否有骨改变以及两者对盘粕连诊断的相关性。结果18例关节盘粘连在CT双对比造影上得到显示;而根据MRI仅诊断关节盘粘连6例.粘连部位在关节给节顶部附近。结论对颞下颌关节盘粘连的显示.CT双对比关节造影较MRI敏感而准确。
Objective To compare the results of CT-assisted double-contrast arthrography and MRI in the diagnosis of adhesion of TMJ. Material 18 patients with adhesion of TMJ were examined by CT-assisted double-contrast arthrography and MRI, and their results were analysed including position. Degree and with or without osseous changes. Results 18 cases of adhesion were demonstrated on CT-assisted double-contrast arthrography. and that only 6 cases of them were diagnosed on MRI. Conclusion CT-assisted double-contrast arthrography is more sensitive and accurate than MRI in demonstrating the disk adhesion of TMJ
