The role of contrast enhanced three-dimensional MR angiography in pulmonary sequestration.

Pulmonary sequestration is a relatively rare but clinically significant form of congenital broncho-pulmonary foregut malformation. It is characterized by a segment of non-functioning lung parenchyma that receives its blood supply from anomalous systemic arteries. This report shows the role of contrast enhanced three-dimensional MR angiography, which demonstrated abnormal feeding artery to the sequestered from the thoracic aorta with draining pulmonary veins.
