目的　通过对腰椎间盘CT平扫与CT脊髓造影 （CTM）的影像表现对照观察 ,提出“盘黄间隙”的概念 ,分析其狭窄的原因及其对腰神经根压迫的诊断意义。方法　回顾性分析 83例腰椎间盘CT平扫与CTM的影像资料 ,分别记录L3～S1腰间盘形态 ,双侧黄韧带厚度 ;双侧上关节突内突程度及相应硬膜囊前后径。分析这些结构及数据与盘黄间隙狭窄及其对腰神经根压迫的关系。结果138个间盘突出或膨出 ,相应硬膜囊前后径 5mm ;6 7侧上关节突增生内突 ,且超过 2mm。盘黄间隙为腰间盘平面位于椎管外侧份间盘与黄韧带之间的间隙。 15 7侧显示腰神经根或根鞘受压 ,相应盘黄间隙平均宽度为 3 8mm。结论　盘黄间隙≤ 5mm即...

Objective To compare the imaging findings of CT non contrast (CTNOC) and CT myelography(CTM) in lumbar intervertibral disk, we proposed a new concept of intervertibral disk flavum ligamentum space(DFLS),analyzed the causes of stenosis in lumbar DFLS and evaluated its diganostic value in compressed lumbar radiculophthy Methods The images of CTNOC and CTM of 83 cases were retrospectively analyzed , and the shapes of L3～S1 disk , the width of flavum ligament at each side, the degree of prominence interior of the joint process superior at each sid...
