Abstract:
Objective To study the imaging characters and diagnostic value of spondylolysis and spondylolisthesis by usingthree-dimensional reconstruction of spiral CT. Methods 37 patients with spondylolysis were scanned by spiral CT.Various reconstruction methods were applied on the data acquired. Results The axial CT scans achieved good resolution on showing hyperostosis,fibrous callus and pathological changes of spinal disc.Spondylolysis was all displayed in the MPR/MIP of sagittal,reverse gantry angle and CPR.MIP,MPRand CPR could provide better resolution in display of spondylolysis than SSD did,while SSD was better in display of hyperostosis andspondylolisthesis. Conclusion The three-dimensional reconstruction of spiral CT is a good method for the radiographic evaluation ofspondylolysis and its relative changes.This technique can provide reliable informations for planning clinical therapy.
