摘　　要：目的探讨椎弓峡部不连的多层螺旋CT(MSCT)表现特点。方法对40例椎弓峡部不连患者行MSCT扫描和三维重建成像。结果40例中发生于L2、L3椎体各1例,发生于L4椎体10例,发生于L5椎体28例。MSCT显示双侧椎弓峡部“裂隙征”40例(100%);“假性椎间盘膨出征”及“椎管宽大征”38例(95%);“椎体游移征”5例(12.5%)。此外,MSCT能够多平面、立体地显示椎弓峡部不连的部位、形态及脊椎滑脱的程度等信息。结论裂隙征是椎弓峡部不连的特征性表现,对椎弓峡部不连具有重要的诊断价值。Objective To study multi - slice spiral CT （MSCT） manifestations of spondyloschisis. Methods 40 patients with spondyloschisis were examined with MSCT scan and 3D reconstruction. Results In the 40 cases, CT scans showed spondyloschisis of the lumbar in L2 （ 1/40 ）, L3 （ 1/40 ）, L4 （ 10/40 ）, Ls spondylosehisis of the lumbar in L2 （ 1/40 ）, L3 （ 1/40）, L4 （ 10/10）, L5（ 28/40 ）. MSCT displayed：the ring- scission sign（ 100% ） , the pseudo- bulging of lumbar intervertebral disc and the elongated sign of spinal canal （95%） , and the wavered sign of vertebral body （ 12.5 % ）. The location, shape of spondyloschisis and the degree of spondylolisthesis were demonstrated by MSCT on muhiplanar and 3D. Conclusion The ring - scission sign is the specific sign in diagnosing the spondyloschisis of the lumbar by MSCT. It is of significant value in the detection of spondyloschisis
