目的探讨脊髓纵裂畸形的ＣＴ诊断价值。方法２３例脊髓纵裂，年龄７个月至２０岁，均摄有脊柱正、侧位Ｘ线平片及ＣＴ平扫，２例行ＣＴＭ检查。结果骨性隔刺２１例，纤维性２例。Ｘ线平片与ＣＴ扫描的诊断阳性率分别为８７％和１００％。讨论ＣＴ扫描对显示脊髓纵裂及椎管形态改变的敏感性高于Ｘ线平片。ＣＴ平扫结合Ｘ线平片能对大多数的脊髓纵裂及其伴发的脊柱畸形作出全面的了解和评价。
Objective To investigate the value of CT diagnosis of spinal longitudinal deformity. Methods Twenty - three patients with longitudinal spinal cord were aged 7 months to 20 years old. All the patients had positive and lateral X - ray films and CT plain scan. CTM examination was performed in 2 cases. 21 cases of septal septum, fibrous in 2 cases. The diagnostic positive rates of X-ray and CT scan were 87% and 100% respectively. Discussion CT scan showed spinal cord longitudinal and spinal morphological changes higher than the X-ray film. CT combined with plain radiography can make a comprehensive understanding and evaluation of most of the spinal longitudinal lobe and its associated spinal deformity.
