Abstract:
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 L_2(1/40),L_3(1/40),L_4(10/40),L_5 spondyloschisis of the lumbar in L_2(1/40),L_3(1/40),L_4(10/10),L_5(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 multiplanar 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
