Abstract:
Objective To explore the ability of different regions of interest(ROI)location settings for the detection of bronchial artery and pulmonary vascular lesions in children with hemoptysis via computed tomography angiography(CTA)examination.Methods The hemoptysis group(79 cases)who underwent chest CTA examination and the control group(79 cases)with negative CTA results were retrospectively selected.The ROI of the hemoptysis group were placed in the pulmonary trunk,left ventricle,ascending aorta and descending aorta,which were defined as groups 1,2,3 and 4 respectively.Clinical data(age,sex)and CT parameters,including bronchial artery diameter,ascending aorta CT value,pulmonary artery CT value,△CTA-PA,bronchial artery image score,pulmonary artery image score,were recorded and analyzed,respectively.Results There was a statistically significant difference in the diameter of the left and right bronchial arteries between the hemoptysis group and the control group(P＜0.05).In the hemoptysis group,there were statistically significant differences in the image scores of the left and right bronchial arteries,pulmonary artery image scores,and△CTA-PA among the four subgroups(P＜0.05).According to post-hoc comparison results,there was a statistically significant difference in the overall mean scores of the right bronchial artery image score(x2=11.333,P＜0.05)and left bronchial artery image score(x2=8.111,P＜0.05)between groups 2 and 3.Conclusion When ROI is placed in the ascending aorta,bronchial artery lesions and pulmonary vascular lesions can be detected simultaneously in CTA examination,which is helpful for the diagnosis of hemoptysis vascular etiology in children.
