| 摘 要： | 目的 :探讨鼻腔及鼻窦解剖结构在螺旋CT仿真内窥镜 (VE)和常规冠状位扫描图像上的显示特点。方法 :经过螺旋CT冠状位扫描或轴位扫描的原始数据被传输到工作站上 ,然后利用NAVIGATOR软件行VE成像 ,调节阈值 ,观察窦口 鼻道复合体等解剖结构 ,测量必要的参数。结果 :鼻甲、鼻道和窦口 鼻道复合体等结构在仿真内窥镜下能更好地被显示 ,骨性解剖显示尤其清晰 ,VE和冠扫两种方法的显示效果有显著性差异(P <0 .0 5 )。因VE显示级别较高 (秩和大 ) ,所以VE的显示效果优于冠扫。钩突、筛泡、半月裂和筛漏斗在VE和冠扫图像上的显示率基本一致 ,额隐窝、鼻额管的显示率较低。结论 :VE显示在评价鼻腔及鼻窦解剖结构方面具有重要的价值 ,有助于放射科及耳鼻咽喉科医师更好地认识其特点 |

| Abstract: | Objective:To evaluate normal and bony anatomy of nasal cavity and paranasal sinus on the spiral CT virtual endoscopy(VE) and coronal scanning image.Method:After patients were scanned on axial or coronal position by spiral CT,data were transferred to workstation.Structures such as ostium-meatal complex(OMC) were viewed by navigator software when threshold was changing.Result:Turbinates?meatus and ostium-meatal complex were better viewed by virtual endoscopy compared with by coronal scanning image.To some extent,bony anatomy was clearer.Conclusion:Virtual endoscopy is of value in realizing characteristics of nasal cavity and paranasal sinus anatomy. |
| Keywords: | X Ray computed tomography Virtual endoscopy Nasal cavity Paranasal sinus |
