螺旋CT重建技术在腰椎峡部裂诊断和治疗中的临床应用价值

Clinical application value of spiral CT and reconstructions in the diagnosis and treatment of lumbar spondylolysis

目的探讨多层螺旋CT(MSCT)及其重建技术在腰椎峡部裂诊断及治疗中的临床应用价值。方法分析2008年～2013年收治的经临床确诊的50例腰椎峡部裂患者的资料,患者均行MSCT扫描图像,所得数据传入工作站,再进行多平面重组(MPR)、容积再现(VR)等图像重组。结果 50例患者的MSCT多种重建技术均可以很好的显示椎体滑脱、峡部裂、骨痂及骨赘形成和纤维组织增生。结论多层螺旋CT扫描及图像后处理可以清晰显示和诊断腰椎峡部裂,为临床手术提供准确的治疗依据。

Objective To explore the clinical application value of spiral CT and reconstructions in the diagnosis and treatment of lumbar spondylolysis. Methods From 2008 to 2013, 50 patients with isthmic spondylolisthesis were admitted to the study. Various post-processing techniques including multi planar reformation （MPR） and volume rendering （VR） were carried out at the workstation. Results MSCT and reconstructions show the vertebral spondylolisthesis, spondylolysis, callus, osteophyte formation and fibrous tissue hyperplasia in all of 50 patients. Conclusion MSCT and imaging post-processing can clear display lumbar spondylolysis and provide accurate preoperative evidence for the treatment of lumbar spondylolysis.
