1、MRI在膝关节半月板桶柄样撕裂中的临床应用价值张云风黄恕坊陶美丽(内蒙古医科大学第二附属医院影像科内蒙古呼和浩特010030)【摘要】目的：探讨MRI对膝关节半月板桶柄样撕裂的诊断价值。方法:对经手术及关节镜证实的46例膝关节半月板桶柄样撕裂患者的MRI表现进行回顾性分析。结果：1152例膝关节损伤患者中，725例患者诊断为半月板损伤，MRI正确诊断46例半月板桶柄样撕裂患者，检出准确率为6.3%。其中发生于内侧半月板者29例，外侧半月板者17例。出现后角残破征20膝(43.48%),领结残破征17膝(36.95%),空领结征16膝(34.78%),双后交叉韧带征20膝(43.4
2、8%),双前角征18膝(39.13%),前角异常肥大征3膝(6.52%),后角异常肥大2膝(4.35%),碎块内移征14膝(30.43%),厚饼征3膝(6.52%),无特殊征象2膝(4.35%)。同时半月板桶柄样撕裂并发前交叉韧带、内侧副韧带损伤的发生比例较高。结论:MRI是诊断半月板桶柄样撕裂的较好方法，空(残)领结征、后角残破征、双后交叉初带征及双前角征是诊断该病的可靠依据。【关键词】膝关节；半月板撕裂；磁共振成像【中图分类号】R445【文献标识码】A【文章编号】2095-1752(2015)11-0072-02ClinicalapplicationvalueofMRIinB
