小儿脊髓纵裂畸形合并脊髓栓系综合征的螺旋CT诊断价值

Evaluation on Diagnosis of Diplomyelia Associated With TCS by Spiral CT in Children

目的探讨螺旋CT(SpiralCT、SCT)在小儿脊髓纵裂畸形(Splitcordmalformation.SCM)合并脊髓栓系综合征(Tetheredcordsyndrome.TCS)中的影像学特点及诊断价值。方法回顾性分析近10年经手术确诊的脊髓纵裂合并脊髓栓系综合征患儿35例,对其术前SCT平扫及多平面重建(Multi-plannnerreformation.MPR)的影像学特点与X线、MRI、临床表现进行对照分析。结果35例患儿术前SCT显示脊髓纵裂者33例,其中I型纵裂23例,与手术所见100%符合;Ⅱ型纵裂10例,符合率83.3%;2例显示不够清楚。结论SCT/MPR诊断脊髓纵裂可获得较满意的图像,是诊断脊髓纵裂的又一重要方法。

Objective To study the features and diagnostic value of spiral CT multiplanner reformation （SCT/MPR） in children with diplomyelia associated with tethered cord syndrome（TCS）. Methods The imaging characteristics of SCT/MPR were analyzed and compared with X-ray, MRI, clinical features in 35children with diplomyelia in recent 10 years. Results 33 cases of diplomyelia was diagnosed by SCT,of them,23 cases were type Ⅰ,10 cases were type Ⅱ and the other 2 diplomyelia were not clearly imaging, the coincidence rate with the operation findings in type Ⅰ and Ⅱ were 100% and 83.3% respectively. Conclusion SCT/MPR can provide a satisfactory imaging data for surgery in children with diplomyelia,at the same time, it is also another an important way in diagnosing it.
