| 摘 要： | 目的 探讨螺旋CT薄层扫描及其图像后处理技术在复杂骨折诊断中的应用,并与常规X线图像、常规轴位CT图像所得诊断结果进行比较.方法 回顾性分析61例解剖结构复杂部位外伤性多发骨折病例,所有病例均行常规X线摄片、常规轴位螺旋CT扫描及薄层轴位螺旋CT轴位扫描后行图像后处理.结果 全部61例骨折受检者,三种方法均能对所有病例之多数骨折作出诊断,但其诊断准确性存在差异,常规X线平片为79.0%、常规轴位螺旋CT扫描为88.5%、薄层螺旋CT扫描图像后处理技术为98.6%(χ2=40.57,P＜0.001)结论常规x线平片可对复杂解剖部位的绝大多数多发骨折作出正确诊断,但假阴性高.常规轴位螺旋CT扫描次之.薄层螺旋CT扫描及图像后处理为三种方法中诊断准确性最高的方法.
