摘　　要：目的探讨儿童气道螺旋CT冠状扫描体位与成像效果的关系。方法回顾分析2008年7~12月44例气道螺旋CT冠状扫描影像资料,结合体位的设置及测量扫描线与气管长轴的角度探讨冠状扫描的气道显示效果。结果气道显示效果佳者33例,扫描线基本与气道平行,最大角度小于2°;效果一般者8例,扫描线与气道成5~10°角;效果差者3例,扫描线与气道角度大于12°。结论螺旋CT冠状扫描显示儿童气道全程佳,体位的设置直接影响气道全程的显示效果。Objective To explore the relation of imaging effect and coronal scan position of spiral CT on children′s airway.Methods Reviewed the images of spiral CT coronal scan on the 44 cases from July to December,2008,to explore the airway show effect of coronal scan to combine the position design and measurement the angle of scan line and air way long axial.Results The effect of airway showed well in 33 cases,with the scan line parallel airway,the largest angle〈 2°,common in 8 cases with the scan line were angled 5-10° with airway,bad in 3 cases with the scan line were angled〉 12° with airway.Conclusion The airway show of children are well with spiral CT coronal scan,the scan position to direct affect the view effect of airway.
