- CT of the Bronchial Arteries
- The bronchial arteries arise directly from the descending aorta and supply blood to the airways, esophagus and lymph nodes
- The left bronchial arteries arise from the anterior surface of the aorta or the concavity of the arch
- The right bronchial arteries arise from the posterolateral aspect of the thoracic aorta
- Bronchial Artery Aneurysm: Etiologies
- Bronchiectasis
- Mycotic origin
- Osler Weber Rendu sydrome
- "A bronchial artery with a diameter of greater than 2 mm is considered to be abnormal and may be the source of hemoptysis. Extravasation of contrast medium, a specific sign of bronchial bleeding is occasionally seen; its reported prevalence is 4-11%."

- "By providing thin section transaxial,multiplanar reconstruction, and 3D images, CT angiography using MDCT allows comparable or better images than conventional
angiography with respect to the depiction of bronchial or nonbronchial systemic arteries."
