CT与MRI联合成像在制定脊髓纵裂畸形手术方案中的价值

目的 探讨CT与MRI联合成像在制定脊髓纵裂手术方案中的价值.方法 回顾分析13例手术证实脊髓纵裂患者术前CT及MRI扫描的影像表现,与手术结果对照分析.结果 发生于腰椎段11例,胸椎段1例,1例同时累及胸椎、腰椎段.13例患者的14个病变中,Ⅰa型7个,其中骨性分隔5个;Ⅰb型3个,1个为骨性分隔;Ⅱ型4个.结论 CT和MR两种检查方法对脊髓纵裂病变的诊断均存在不足之处;联合成像可以相互补充,能更全面对脊髓纵裂分型和并发病变做出明确诊断,为手术提供更为全面的诊断信息;术前CT和MRI联合成像应该成为检查常规.

Diagnostic value of CT combined MRI imaging in the formulation of the operation scheme of diastematomyelia

Objective To investigate the diagnostic value of CT combined MRI imaging to formulate the operation scheme of diastematomyelia.Methods The CT and MRI features of 13 cases confirmed by operation of diastematomyelia were reviewed preoperatively and compared with the results of the operation.Results The diastematomyelia was found in lumbar vertebra in 11 cases,in thoracic vertebra in 1 case,and in both lumbar vertebra and thoracic vertebra in 1 case.In the 13 patients,a total of 14 lesions were proved by operation,including 7 cases of type Ia （including 5 cases of bony septum）,3 cases of type Ib （1 case ofbony septum）,and 4 cases oftype Ⅱ.Conclusion CT or MR is inadequate in diagnosis of diastematomyelia.The combination of CT and MRI can complement each other,determine types of diastematomyelia and associated malformations,provide more comprehensive diagnostic information for surgery,which should serves as a routine examination.
