摘　　要：目的 :探讨仰卧式头架螺旋CT鼻腔及鼻窦冠状位扫描时机器摆动角度范围对冠状成像质量的影响。材料与方法 :对 1999年 8月～ 2 0 0 0年 10月门诊及住院患者 117例行鼻腔及鼻窦冠状位扫描 ,采用仰卧式头架 ,对一些病例采用近似冠状位扫描 ,将所有图像均进行三维重建。结果 :与OML成 6 7°～ 90°的近似冠状位扫描基本能满足依赖冠状位鼻腔及鼻窦CT图像诊断的需要。结论Purpose:To investigate effect of gantry angle on spiral CT coronal imaging of nose and paranasal sinus.Materials and Methods:177 Patients were scanned by spiral CT and supine gantry were applied.All patients were scanned in coronal position or approximately coronal position and 3D reconstruction was performed.Results:67°～90° to OML is the useful angle extention in diagnosing,by spiral CT coronal imaging of nose and paranasal sinus.These imaging can provide reasonable data for Radiology and Clinics.Conclusion:Approximately coronal scanning is the choice of Radiology in some cases.
