【摘要】 目的探讨鼻窦MSCT检查的质量控制。材料与方法分析随机选取的83例鼻窦64层CT检查的不同参数重建和不同窗技术所获得的A、B、C、D四组鼻窦CT图像,比较分析其对鼻窦解剖细节的显示良好程度。结果 A、B、C、D四组图像中,以D组显示最佳。螺旋容积扫描、薄层骨窗摄片、以冠状位与横轴位为主的多方位图像能良好显示鼻窦以及临近结构解剖。结论螺旋容积扫描、薄层骨窗摄片、以冠状位与横轴位为主的多方位图像能良好显示鼻窦以及临近结构解剖,为鼻内镜手术提供详细准确的解剖信息,提高手术的成功率并减少或避免手术并发症的发生,保证鼻窦MSCT检查的良好质量控制。更多还原

【Abstract】 Objective To study the quality control of paranasal sinus MSCT examination.Methods Analysis the 83 cases CT images of paranasal sinus,which were selected randomly from 64-slice CT scanning with different reconstruction parameters and different window technologies,the images were divided into A,B,C,D four groups.Analysis the anatomy detail of the paranasal sinuses comparatively.Results The group D is the best of four group,It is well showed on paranasal sinus anatomy and adjacent structures with spiral volumetric scanning,thin bone window images,multi-dimensional images which based on coronal and axial.Conclusion It is well showed on paranasal sinus anatomy and adjacent structures with spiral volumetric scanning,thin bone window images,multi-dimensional images which based on coronal and axial.It is valuable for endoscopic sinus surgery,providing detail and accurate anatomical information,improving the success rate of surgery and preventing surgical complications.更多还原
