Abstract

PURPOSE

To determine the impact of patient positioning and scan orientation on the appearance of air in the nasolacrimal drainage system on computed tomography (CT) imaging, and the repeatability of the observations.

METHODS

This was a retrospective analysis of CT images for 92 patients.

RESULTS

Air was found to be present more fully in the upright-position group as compared with the supine-position group. Comparing axial and coronal scan orientation, no difference in aeration was found, except for the nasolacrimal duct in the upright-position group.

CONCLUSION

Patient position should be accounted for in diagnostic conclusions and treatment decisions based on CT.

摘要

目的

确定患者体位和扫描方向对计算机断层扫描（CT）成像中鼻泪引流系统内空气表现的影响，以及观察结果的可重复性。

方法

这是一项对92例患者的CT图像进行的回顾性分析。

结果

与仰卧位组相比，直立位组鼻泪引流系统内的空气显示更充分。比较轴位和冠状位扫描方向，除直立位组的鼻泪管外，通气情况无差异。

结论

基于CT的诊断结论和治疗决策应考虑患者体位。
