Figure 3b. (a) Maximum intensity projection and (b) volume-rendered CT images in a 51-year-old woman with tuberculosis and recurrent episodes of massive hemoptysis show a right bronchial artery (arrowheads) of 3.2 mm in diameter arising from right internal mammary artery (arrows). Selective right internal mammary angiography was not performed because aortogram (not shown) did not show this vessel.
