摘　　要：目的:探讨螺旋CT多层面容积重建对腰惟峡部裂的诊断价值。方法:选取行腰椎螺旋CT检查的50例腰痛患者资料,根据椎弓有无峡部裂分成峡部裂组(25例,有峡部裂)和对照组(25例,无峡部裂),所得数据资料行t检验。结果:峡部裂主要发生在L5(18例,占72%),腰椎峡部裂常导致腰椎前滑脱(24例,占96%)。峡部裂组椎管矢状径明显大于对照组椎管矢状径,之间有显著性差异(P<0.01),峡部裂组峡部高小于对照组峡部高,之间有显著性差异(P<0.05)。结论:螺旋CT扫描MPVR重建图像可以从骨性和软组织两个方面为临床提供更多影像学信息。Objective： To discuss the diagnostic value of helical CT multi-plane volume reconstruction which was used to evaluate lumbar spondylolisthesis. Methods： To select 50 patients who were examined by helical CT, according to clinical characteristics, 50 patients were divided into two groups： the group one （25 cases） with spondylolisthesis and the group two （25 cases） without spondylolisthesis, t-test was used to test the results. Results： Spondylolisthesis take place mainly in L5, （18 cases, 72%）, the lumbar spondylolisthesis often lead to vertebral spondyloptosis, （24 cases, 96%）, the sagittal line of the group one wassignificant larger than the group two, there are significant difference between the two groups （P 〈 0.01）, the hightness of vertebral isthmus was significant larger than the group two, there are also significant difference between the two groups （P 〈 0.05）. Conclusion： The image of helical CT multi-plane volume reconstruction could offer more image information from bone and soft tissue factors than the others.
