摘　　要：目的探讨腰椎硬膜外造影后多排螺旋CT检查(MSCTE)方法和临床应用价值。方法采用128层64排螺旋CT对30例患者进行扫描、三维重建,进行CT、MRI和MSCTE影像学对比研究,分析MSCTE影像特点。结合手术探讨MSCTE临床应用价值。结果改进的硬膜外造影方法可以得到满意的三维影像资料。椎管内软组织界限表现力MSCTE优于MRI和CT,同时还兼有CT的骨显示优势。结论MSCTE是一种安全、有效的影像学检查方法,不仅可用于椎间盘突出和椎管狭窄的诊断,还适用于CT和MRI难以明确的椎管内隐蔽病变的发现和诊断。Objective To investigate the clinical application of multispiral CT scanning （MSCTE） after lumbar epidurography. Methods There were 30 patients performed epidurography and multispiral CT scanning with advanced 128 layers of 64-slice and three-dimensional reconstruction. The imaging features were contrasted with CT and MRI imaging. Combined with intraoperative findings, the value of MSCTE to clinical application was analyzed. Results The improved epidurography can get satisfing three-dimensional image data. The extent of soft tissue with MSCTE was clearer than that with MRI and CT. Conclusions MSCTE is a safe and effective imaging examination. MSCTE can be used on lumbar disc herniation and spinal stenosis diagnosis, which is suitable for the patients that were difficult to detect and diagnose with CT and MRI.
