【摘要】 目的 探讨多层螺旋CT曲面重建成像在诊断腰椎小关节病中的应用价值。方法 对42例临床拟诊腰椎小关节病患者行L2～S1多层螺旋CT平扫，并对腰椎小关节进行多角度曲面重建成像。结果 本组共诊断腰椎小关节病35例，其中关节突增生、硬化、变形19例；关节间隙左右不对称变窄或增宽32例；关节面毛糙17例；关节间隙内真空征11例。结论 多层螺旋CT曲面重建成像能全面、直观地显示腰椎小关节，为腰椎小关节病的诊断提供了可靠的影像学依据。

    【Abstract】 Objective To explore the value of curvature plane reconstruction(CPR) with multislice spiral CT(MSSCT) in the diagnosis of lumbar vertebral arthrosis(LVA).Methods The axial scanning from the second lumbar vertebral to the first sacral vertebral and multi-angle CPR with MSSCT were performed.Results 19 cases of arthrosclerosis or joint hyperplasia and deformity,32 cases of broaden or stenosis of the joint space,17 cases of unsmooth articular surface and 11cases of vacuous articular space were found in 35 cases of LVA from 42 patients.Conclusion CPR with MSSCT can reveal lumber vertebral small joint overall and directly and provide dependable image basis for the diagnosis of LVA. ......
