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。方法自2007年12月至2009年2月,共完成了MSCTE检查30例。对硬膜外造影方法进行了改进,用当前先进的128层64排螺旋CT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,同时还兼有了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。MSCTE检查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 lumbar epidurography and multispiral CT scanning examination and its clinical application.Methods There were 30 patients performed epidurography and multispiral CT scanning in Dec/2007 to Feb/2009.Ways of epidurography is improved,then the current advanced 128 layers of 64-slice spiral CT scan,three-dimensional reconstruction.To investigate imaging features contrast with CT and MRI imaging,and analysis MSCTE imaging characteristics.Combined with intraoperative findings,analysis MSCTE value to clinical application.Moreover,there are advantages of bone imaging.Results The Improved epidurography can be satisfied with the three-dimensional image data.Show the extent of soft tissue MSCTE better than MRI and CT.Conclusions MSCTE is a safe and effective imaging examination.MSCTE can be used not only lumbar disc herniation and spinal stenosis diagnosis,but also suitable with CT and MRI difficult to detect and diagnose intraspinal disease.
