CT对腰椎退行性变的诊断价值

目的探讨ＣＴ在诊断腰椎退行性变中的价值。方法回顾分析３００例腰椎退行性变的ＣＴ检查资料，找出其影像变化的特征。结果在３００例ＣＴ诊断为腰椎退行性变的病例中，表现为：（１）椎体骨质增生１９４例，占６４７％；（２）椎间盘膨出１１０例，占３６７％；（３）椎间盘突出９７例，占３２３％；（４）椎小关节病９７例，占３２３％；（５）椎间盘膨出和突出６１例，占２０３％；（６）退变性骨性椎管狭窄中央型２３例，占７７％；侧隐窝狭窄１９例，占６３％；（７）黄韧带肥厚１８例，占６０％；（８）退变性脊椎滑脱６例，占２０％；（９）真空现象５例，占１７％。结论ＣＴ检查不仅能明确腰椎退行性变的诊断，而且能为临床表现的解释和治疗提供更多的信息和依据。

Value of CT in diagnosis of degenerative lumbar spine

Objective To explore the diagnostic value of CT in degenerative lumbar spine.Methods The findings of 300 cases of degenerative lumbar spine diagnosed by CT were retrospectively analysed and the characteristics of the findings were compared.Results The characteristic CT findings in the 300 cases of degenerative lumbar spine were 1)vertebral hyperosteogeny in 194 cases(64.7%),2)bulging of intervertebral disk in 110(36.7%),3)protrusion of intervertebral disk in 97(32 3%),4)facet osteoarthritis in 97(32.3%),5)bulging and protrusion of intervertebral disk in 61(20.3%),6)degenerative osteostenosis of spinal canal (central type) in 23( 7.7% ),7)stenosis of lateral recess in 19(6.3%),8)hypertrophy of ligamentum flavum in 18(6.0%),9)degenerative spondylolisthesis in 6(2.0%) and 10)vaccum phenomenon in 5(1.7%).Conclusion CT examination can not only make definife diagnosis of degenerative lumbar spine but also provide information for explanation of clinical manifestation and treatment of this disease.
