The value of post-processing technique of 64-spiral CT in diagnosing lumbar spondyloschisis

Objective To evaluate the value of imaging reconstruction technique of 64-slice spiral CT in diagnosing lumbar spondyloschisis.Methods 38 patients with lumbar spondyloschisis underwent by 64-slice spiral CT.The data were transmitted to workstation and the images were reconstructed with the techniques of multi-planar reconstruction(MPR),volume rendering(VR) and curved planar reconstruction(CPR) in order to observe the lumber spondyloschisis,the slip of upper lumbar,the change of interertebral disc,and the change of surrounding bones.Results 77 lumbar spondyloschisis were found in 38 cases,in which 29 cases were the degree I slip of upper lumbar,5 cases were the degree II slip of upper lumbar,1 case was the degree III slip of upper lumbar;The display rates of spondylochisis by MPR and VR was the highest,which were 100% and could find clearly the position,length of the lumbar spondyloschisis,the change of around bones.Conclusion The 64-slice spiral CT and the imaging reconstruction technique have higher value in diagnosing lumbar spodyloschisis,which can provide more valid information for clinicians.
