Figure 1d. (a) Transverse 1.25-mm-thick and oblique (b) sagittal and (c) coronal 1.0-mm-thick CT images with MPR in a 35-year-old man with bronchiectasis and episodes of nonmassive hemoptysis show a left bronchial artery (arrow) of 3 mm in diameter. It arises from the aorta at the level of T6 and is traceable to the hilum.
