关节骨折的螺旋CT三维重建评价

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Philips Aura螺旋CT对31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,减少手术创伤。

The value of spiral CT with 3D imaging reconstruction in articular fracture

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.
