【摘要】 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。更多还原

【Abstract】 Objective To investigate the diagnostic value of CT combined MRI imaging to formulate the oper- ation scheme of diastematomyelia. Methods The CT and MRI features of 13 cases confirmed by operation of diaste- matomyelia were reviewed preoperatively and compared with the results of the operation. Results The diastematomy- elia 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(includ- ing 5 cases of bony septum), 3 cases of type Ib(1 case of bony septum), and 4 cases of type Ⅱ. Conclusion CT or MR is inadequate in diagnosis of diastematomyelia. The combination of CT and MRI can complement each other, de- termine types of diastematomyelia and associated malformations, provide more comprehensive diagnostic information for surgery, which should serves as a routine examination.更多还原
