摘　　要：目的探讨双源CT五种图像重建方法在腰椎弓峡部裂(LS)诊断中的价值。方法对60例LS患者行双源CT检查,扫描数据分别采用五种方法进行图像重建,观察LS诊断率。结果60例患者共检出峡部裂114处,LS诊断率椎间盘横断面多平面重组(MPR)为0,椎弓反角度MPR为86.0%(98/114),矢状位MPR为100.0(114/114),斜横断位曲面重建(CPR)为100.0(114/114),容积再现(VR)为80.7%(92/114)。矢状位MPR及斜横断位CPR诊断率显著高于椎弓反角度MPR及VR,P均<0.01。结论采用腰椎矢状位MPR和斜横断位CPR重建双源CT图像诊断LS更准确、直观。Objective To investigate the value of five kinds dual source CT image reconstruction methods in the diagnosis of lumbar spondylolysis（KS）. Methods Sixty 60 cases of LS were performed with daul source CT examination, the scanning datas were reconstructed using five kinds of dual source CT image reconstruction methods, the diagnosis rate of LS was observed. Results One hundred and fourteen sites of lumbar spondylolysis were found in these 60 cases. The diagnosis rate of LS got by multi-planar reformation（MPR） was 0 ,got by reverse-angle MPR of arcus vertebrae was 86.0% （98/ 114）, got by sagittal MPR was 100.0% （114/114）, got by curved planar reformation（CPR） was 100.0% （114/114）, got by volume rendering（VR） was 80.7% （92/114） ,the diagnosis rate of LS got by sagittal MPR and CPR were significantly higher than that got by reverse-angle MPR of arcus vertebrae and VR, all P 〈 0.01. Conclusion To diagnosis the LS with the image reconstruction methods of sagittal MPR and CPR is accurate and visual.
