title: Multidetector CT of bronchial and non-bronchial systemic arteries.
abstract: We evaluate the use of multidetector row computed tomography (MDCT) angiography for the depiction of bronchial and non-bronchial systemic arteries (NBSAs), which frequently become enlarged as a secondary finding in a wide array of chronic lung diseases and other diseases that affect the pulmonary vascular system. MDCT angiography has enabled radiologists to provide thin-slice axial images, multi-planar reconstructions, interactive maximum intensity projections, and volume-rendered images to evaluate the origin and course of the abnormal bronchial arteries and enlarged NBSAs that may be the cause of hemoptysis. Embolization of the bronchial arteries is the primary treatment option in patients with massive hemoptysis. Precise localization of the bleeding vessel(s) prior to catheter arteriography not only is the most important factor for prompt and successful embolization but also prevents the recurrence of hemoptysis from missed NBSAs during procedures.
