Morphological Analysis of Bronchial Arteries and Variants with Computed Tomography Angiography

Figure 2

Ostium location methodology for bronchial arteries. (a) is cross-section of a thoracic CT scan when the origin is from the thoracic aorta, and (b) is a coronal section of a thoracic CT scan when the origin is from the aortic arch. Assessment of the ostium location of each bronchial artery at its origin is completed using the methodology described by Battal et al. [23]. am = anterior-medial, al = anterior-lateral, pm = posterior-medial, and pl = posterior-lateral.
