Application Value of Post-processing Technique of 64-slice Spiral CT in Diagnosing Lumbar Spondyloschisis

Objective To evaluate the value of post-processing technique in diagnosing lumbar spondyloschisis using 64-slice CT.Method Fifteen patients with lumbar spondyloschisis were underwent by 64-slice spiral CT.The data was transmitted to 3D workstation and the images were reconstructed with the techniques of multiplanar reconstruction(MPR),volume rendering(VR) and curved planar reconstruction (CPR) in order to observe the lesions of spondyloschisis.Results The display rate of spondyloschisis by MPR,VRT and CPR were 100%(23/23),73.9%(17/23),100%(23/23),95.7%(22/23), 100%(23/23) respectively.All spondyloschisis can be totally showed by one image of CPR.Conclusion The post-processing technique of 64-slice CT yields more information of morphologic change of the lumbar spondyloschisis,providing more valid information for clinicians.
