| 摘 要： | 目的:探讨螺旋CT对窦口鼻道复合体(OMC)的最佳冠状位扫描方式和成像效果。方法:对106例门诊患者行鼻腔及鼻窦冠状位3mm薄层扫描,56例采用标准冠状位扫描,50例采用冠状倾斜位扫描,将所有图像均进行多平面(MPR)及三维(3D)重建。结果:冠状倾斜位薄层扫描对钩突、中鼻甲、筛泡、半月裂、筛漏斗的显示情况与薄层标准冠状位扫描无明显差异(P>0.05),但对额窦引流通道的显示优于标准冠状位薄层扫描(P<0.05)。结论:螺旋CT冠状倾斜位薄层扫描能全面显示OMC的结构,尤其能良好显示额窦的引流通道,是显示OMC的最佳扫描方式。

| Abstract: | Objective:To research for a better coronal position scanning method of the Spiral CT in the Ostiomeatal Complex.Methods:106patients' sinuses were scanned with Spiral CT in the coronal position in3mm-thick layers,56cases of them in the standard coronal position and50cases in the coronal oblique thin-slice scanning technique.MPR and3D reconstruction were performed.Results:the coronal oblique thin-slice scanning method produced the same result as the standard coronal thin-slice scanning(P>0.05)in displaying the uncinate,middle turbinate,ethmoidal bulla,hiatus semilunaris and ethmoidal in-fundibulum,but it displayed the frontal drainage channel better(P<0.05).Conclusion:the structures of the OMC,especially the drainage channel of frontal sinus,can be better demonstrated with coronal oblique thin-slice scanning technique,and thus it can be a valuable choice of radiology. |
