目的 探讨螺旋CT多平面重建 (SCTMPR)在儿童脊髓栓系综合征 (TCS)诊断中的应用。资料与方法 对 118例TCS患儿行SCT平扫 ,然后进行MPR。结果 118例TCS患儿中脊髓低位 111例 ,脊髓位置正常 7例。低位脊髓合并脊髓纵裂者 12例 ,椎管内脂肪瘤 2 4例 ,椎管内皮样囊肿 9例 ,脊髓空洞症 9例 ,半椎体及蝴蝶椎 12例 ,棘突缺如或分叉 16例。脊髓位置正常合并脊髓空洞症 2例 ,脊髓纵裂 3例。 118例TCS患儿中 112例伴有脊柱裂(占 94.9%)。其中包括 14例隐性脊柱裂及 98例显性脊柱裂。通过MPR均能获得较满意的图像 ,满足诊断的需要。结论 MPR可以较全面、立体、直观地显示TCS患者脊髓及脊椎的情况 ,是继MRI之后诊断TCS的又一重要方法。
Objective To investigate the application of spiral CT multiplanar reconstruction (SCTMPR) in the diagnosis of children with tethered cord syndrome (TCS). Materials and Methods 118 cases of TCS children with SCT plain scan, and then MPR. Results Among 118 children with TCS, 111 cases were found with low spinal cord and 7 cases with normal spinal cord position. 12 cases of low spinal cord combined with spinal longitudinal splitting, 24 cases of intra-oral lipoma, 9 cases of spinal endothelium-like cysts, 9 cases of syringomyelia, 12 cases of hemivertebra and butterflies, missing or branched spinous process example. Spinal cord position with normal syringomyelia in 2 cases, 3 cases of spinal longitudinal splitting. One hundred and thirteen cases of 118 children with TCS had spina bifida (94.9%). Including 14 cases of latent spina bifida and 98 cases of dominant spina bifida. By MPR can get more satisfactory images to meet the needs of diagnosis. Conclusion MPR can show the situation of spinal cord and spine of TCS patients more comprehensively, stereoscopically and intuitively. It is another important method to diagnose TCS after MRI.
