Figure 4: Pulmonary vein stenoses. (a and b), Ventilation-perfusion scans: preserved ventilation (a) and decreased perfusion (b) of the left lung and the superior segment of the right lower lobe (arrowhead). (c) Chest radiograph: Pulmonary edema. (d-f) Axial electrocardiography-gated contrast-enhanced cardiac computed tomography angiograms: (d) mild/moderate right superior pulmonary vein ostial narrowing (arrowhead) and abnormal tissue surrounding ostium (*); (e) moderate/severe right inferior pulmonary vein ostial stenosis (arrowhead) and surrounding soft tissue (*); (f) left superior pulmonary vein ostial stenosis and poor left superior pulmonary vein opacification (arrows). Note: image (d) is the same as image (f). LT: Left; POST: Posterior; RT: Right
