Abstract:
Objective To study the method and ability of multi-slice CT isotropic scan and post-processing in displaying the anatomy of cervical vertebrae.Methods The normal cervical spines in 53 cases were scanned with isotropic parameters using 16-slice-helical CT.All the images were post-processed with the methods of MPR,MIP,SSD and VRT and each other were compared between them,then the best one was selected to compare with axial CT images and plain films.The abilities in displaying inter-vertebrae disc,spinal canal longtitude,vertebrae body,vertebral arch,zygapophyseal joint and inter-vertebrae foramen were compared among the 3D reconstruction,direct CT scan and X-ray plain film including post-anterior,lateral,left-anterior oblique and right-anterior position project.Results The quality of isotropic post-processing images had no remarkable differences with that of direct CT scan in showing inter-vertebrae disc,but it was better than X-ray plain film and conventional CT scan mode in showing other structures.Conclusion The multi-slice helical isotropic CT scan and post-processing images are of great value in the study of cervical spine.
