Anomalies and Malformations of the Pulmonary Circulation

Congenital anomalies of the pulmonary circulation can be seen as isolated anomalies or as part of more complex malformations affecting numerous organs and systems, in particular the lungs, heart, and great vessels. These malformations may affect the pulmonary arteries, pulmonary veins, the aorta, and the intrathoracic systemic veins. With its superb spatial and temporal resolution, contrast-enhanced multidetector CT has become the imaging modality of choice for the evaluation of these entities, allowing imaging of the heart, vasculature, and lungs in one single examination.
