摘　　要：目的 :探讨脊髓纵裂畸形的MRI诊断价值。材料与方法 :共 18例 ,男 13例 ,女 5例 ,11个月～ 37岁 ,14岁以下 15例。结果 :18例脊髓纵裂共累及胸6～骶1节段脊髓。同时累及 2节段脊髓 8例 ,3节段 1例 ,4节段 4例 ,5节段 2例 ,7节段 2例 ,9节段 1例。无间隔型 16例 ,占 88 9% ,有间隔型 1例占 5 5 % ,两型同时存在 1例。结论 :MRI是诊断脊髓纵裂畸形最准确有效的非创伤性检查方法 ;它可以从不同方位显示脊髓纵裂的部位、范围和形态 ;MRI同时还可以显示脊髓纵裂合并的其他异常 ,如脊髓空洞、栓系、低位及椎管内占位病变 ;MRI可以准确发现先天脊柱畸形有无脊髓异常 ,为临床提供手术方案有非常重要意义。Purpose:To explore the diagnostic value of MRI for diastematomyelia.Materials and Methods:18 cases ranged from 11 months to 37 years in age,13 were males and 5 were females,among which 15 cases were less than 14 years old.Results:From T 6 to S 1 segments of spinal cord were being involved.In the same patient there were 2 segments of spinal cord being involved of 8 cases,3 segments of 1,4 segments of 4,5 segments of 2, 7 segments of 2, 9 segments of 1.The spinal cord was divided into two parts without septum in 16 cases,constitute 88.9%.The remains 1 with septum,another both with septum.Conclusion:MRI was the most exact and effective no traumatic method for diagnosis of diastematomyelia.Other anomalies could be showed by MRI such as syringomyelia,tethered spinal cord,Low-lying spinal cord and intraspinal tumours.
