摘　　要：目的探讨螺旋CT旁矢状位重建对腰椎间孔狭窄的诊断价值。方法2003-01～2004-04,对腰腿疼患者临床和常规CT检查考虑有椎间孔狭窄时,使用螺旋CT旁矢状位二维重建,诊断并手术腰椎间孔狭窄症15例。结果15例螺旋CT旁矢状位重建均显示有L4～5或L5～S1椎间孔狭窄,2例极外侧型椎间盘突出,8例椎体终板后外缘局限性增生骨化突入椎间孔,1例腰椎滑脱峡部裂假关节,4例后外侧椎间盘突出间隙狭窄并黄韧带肥厚小关节增生、上移。水平狭窄型7例,垂直狭窄型8例。Ⅱ度狭窄6例,Ⅲ度狭窄9例。结论螺旋CT旁矢状位重建可以弥补常规横断CT扫描的不足,对椎间孔显示清晰直观,对手术减压有定位指导意义,有较高诊断价值。Objective To discuss the diagnostic value of parasagittal reconstruction CT for the lumbar intervertebral foraminal stenosis.Methods From Jan.2003 to Apr.2004,15 suspected cases with lumbar intervertebral foraminal stenosis based on the routine clinical and radiologic examinations were diagnosed by means of the CT parasagittal reconstruction and operated on .Results All showed L_(4~5) or L_5~S_1 foraminal stenosis,2 cases far lateral disc protruded,8 cases the vertebral endplate posteriolateral spurs extruded into foramina,1 spondylolisthesis pseudoarthrosis pressed,4 cases had the narrow intervertebral space along with the flavum ligament hypertrophy and facet superioanterio subluxation. 7 cases showed horizontal stenosis and 8 cases showed vertical stenosis.6 cases wereⅡ°,9 cases were Ⅲ°. Conclusion The parasagittal reconstruction CT for the lumbar foraminal stenosis can compensate for the drawbacks of the routine axial CT, show more clearly and vividly and guide the operations more accurately.
