脊髓纵裂畸形的ＭＲＩ诊断

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华人裂的部位、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，为临床提手术方案有非常重要意义。

The Diagnosis Value of MRI for Diastematomyelia

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.
