摘　　要：目的 :探讨螺旋CT三维重建技术在关节骨折中的诊断价值。方法 :使用PhilipsAura螺旋CT对 3 1例患者的损伤关节进行容积扫描 ,所得原始数据传送到工作站做三维重建处理 ,显示立体图像 ,并与X线平片及CT平扫比较。结果 :螺旋CT三维重建技术逼真地显示关节骨折的情况 ,与临床实际相符 ,确诊率 96.8%,明显高于X线平片 ( 67.7%)及CT平扫 ( 87.1%)。结论 :螺旋CT三维重建技术能清楚显示关节骨折的细节 ,有利于临床诊断和治疗 。Objective:To evaluate the clinical significance of spiral CT with three dimensional imaging reconstruction in articular fracture.Methods:31 cases of articular fracture were scanned with spiral CT,and the resultant data were processed in workstation for 3D imaging reconstruction.They were compared with X ray and CT plain scan.Results:In all patients,spiral CT with 3D image reconstruction revealed articular fracture in detail,and the coincidence of diagnosis was 100%,which was superior to X ray and CT plain scan.Conclusion:Spiral CT with three dimensional image reconstruction is a noninvasive technique with excellent accuracy in the diagnosis of articular fracture and is helpful in treatment planning and assessment of prognosis.
