由于支气管倾斜、支气管分支难于识别以及可以测量的支气管分支数有限,CT用于气道病变病人的气道面积的评价受到制约。本研究的目的:①分析CT影像上所有可显示的经自动正交重建的支气管横断面面积;②将吸烟者与非吸烟者支气管形态测量进行比较
Due to the bronchial tilt, the bronchial branch is difficult to identify and the number of bronchial branches that can be measured is limited, the evaluation of the airway area of CT for patients with airway disease is restricted. The purpose of this study was to: (1) analyze all available cross-sectional areas of the bronchus that can be automatically and orthogonally reconstructed on CT images; (2) compare the bronchial morphology of smokers with non-smokers
