摘　　要：目的:总结分析191例腰椎间盘突出症的CT及MR1影像特征。方法:CT组104例,MR组87例,同时行CT及MR检查44例。结果:CT组中,椎间盘突出位于L3～4者12例,L4～5者32例,L5～S1者60例。骨质增生31例,髓核钙化11例,后纵韧带钙化9例。MR组中,椎间盘突出位于L3～4者13例,L4～5者39例,L5～S1者35例,椎间盘变性41例。同时行MRl和CT检查44例,11例CT示髓核突出钙化而MRl仅表现椎间盘突出,9例CT示后纵韧带钙化而MR仅示硬膜囊前方脂肪间隙扩大,2例MR1矢状面示脱出的髓核游离于下一椎体上缘而CT于椎间盘层面未观察到。结论:CT及MR1均具有良好的软组织分辨率。CT更优于显示骨性椎管情况,有无骨质增生,髓核及韧带钙化,骨化斑。而MR对显示多个椎间盘突出,变性,有无髓核脱出及脱出的新鲜程度有独特效果。实际工作中,两项检查可互补,以提高椎间盘突出的检出率。Objective:To analyze the CT and MRI findings in 191 cases with lumbar disc herniation. Method: 104 had CT examination. 87 had MRI examination 44 both had CT and MRI examination. Result:In CT group, lumbar disc herniation lie in Lumbar 3 to 4 has 12 case, lubmar 4 to 5 has 32 cases. Lumbar 5 to S1 has 60cases. 31with myelosis,11with calcification fo the herniated disc and 9 with calcification of the sagital ligament. In MRI group, 41 cases show the degeneration of disc. In the group which both have examination of CT and MRI show that CT has the menifestation of calcification of the herniated pulposus nucleus and sagital ligament, but MRI only shows the herniated of disc and extension of fat space be-for duralsac. Conclusion:CT is better to show the vertebral canal, myelosis, ossification, calcification of pulposus nucleus and ligament. Whereas MRI has the significant effects to show the degree and time of the prolapsing pulp nucleus.
