320排 CT 容积扫描对支气管动脉的解剖学研究价值
Study value of 320-detector CT volume scanning in anatomy of the bronchial arteries❋
摘要
Abstract
Obj ective :To explore the research value of 320-detector computed tomography (320-DCT)in displaying anatomic structures of the bronchial arteries.Methods :A total of 144 patients underwent enhanced chest CT scan.3-dimensional reconstruction of the arteries was performed using different post-processing techniques including multiple planar reconstruction (MPR),maximum intensity projection (MIP)and volume rendering (VR).Spatial anatomical characters of the bronchial arteries were observed and recorded,such as the type of branches,origin and opening position of the bronchial arteries.The images of the bronchial arteries and bronchial tree were fused together,which could display the 3-dimensional structures of the bronchial arteries more directly and three-dimensionaly.Results :In 144 patients,393 bronchial arteries were identified (1 77 on the right and 21 6 on the left),and the most common type of the bronchial arteries was R1 L1 (45.8%).The right bronchial arteries mainly originated from the intercostal artery (54.2%),while the left bronchial arteries mainly originated from the descending aorta and aortic arch (86.1 %).The right bronchial arteries of the descending aorta mainly arose from the right wall and the anterior wall,while the left bronchial arteries of the descending aorta mainly arose from the anterior wall of the aorta.When positioning the tracheal bifurcation,the left and right bronchial arteries mainly arose from 2 cm above and 1 cm below the tracheal bifurcation,accounting for 88.1 % and 84.7% respectively.Conclusion:320-DCT could clearly display the origin and the opening position of the bronchial arteries as well as the number of branches,thus providing detailed three-dimensional anatomical characters for interventional treatment through the bronchial arteries.关键词
