Fig 2.
MDCT in a 4-year-old boy with PA-VSD.
(a) Axial CT shows the patients has patent ductus arteriosus(*). Some MAPCAs (white arrow) from the descending aorta (DAo) to the right lung. (b) Axial CT demonstrates good-sized right pulmonary artery (RPA) and left pulmonary artery(LPA). The orifice of a MAPCA (#) is depicted clearly. (c) 3D Volume-rendered image (posterior view) shows a MAPCA (white arrowhead) from the descending aorta to the right lung.

(a) 3D Volume-rendered image (posterior view) shows MAPCA (white arrowhead) from descending aorta and left subclavian artery in a 2-year-old boy with PA-VSD. (b) Another 6-year-old girl with PA-VSD.
3D Volume-rendered image (posterior view) demonstrates a stenosis (white arrow) on a MAPCA from left subclavian artery.

Imaging in a 3-year-old boy with PA-VSD.
3D Volume-rendered image with electronic dissection, which remove contrast from the cardiac chambers, shows the defect (*) in ventricle septum (VS) and the overriding aorta (<50%). AAo indicates ascending aorta.
