摘　　要：目的:探讨腰椎MSCT检查中隐性脊柱裂漏诊的原因及避免方法。方法:回顾性分析300例行MSCT腰椎扫描的病例,找出隐性脊柱裂的病例并行图像后处理形成A、B两组诊断图像,A组为常规横断面图像,B组为横断面、冠状面MIP及VRT的组合图像,3位诊断医师在提示前与提示后两次观察两组图像并给出诊断报告,统计各组脊柱裂的漏诊情况。结果:300例患者中,发现隐性脊柱裂58例,漏诊率A组高于B组,第一次高于第二次。结论:隐性脊柱裂在腰椎MSCT检查中常被忽略,利用图像后处理技术,能有效避免漏诊,并进一步分型。Objective：To discuss the reasons of missed diagnosis of spina bifida occulta （SBO） in spinal multislice CT and the solution to avoid it. Methods：Review the CT findings of 300 cases who underwent CT spinal exam and find out the cases of SBO,then run image postprocessing＇to form two groups diagnosis image as A and B. Group A contain the conventional transverse images and group B include transverse MPR, coronal MIP and VRT images. Three diagnostician reading the two groups images before and after hint and make a diagnosis for each case. Analyses the missed diagnosis of SBO between the different groups. Results：58 cases of SBO were found in 300 patients. The mis-diagnosis of SBO in group A were higher,the first time is higher than the second. Conclusion： SBO is often ignored in spinal CT exam. Image postprocessing techniques is helpful to avoid mis-diagnosis and type SBO.
