Application of helical computed tomographic angiography with differential color imaging three-dimensional reconstruction in the diagnosis of complicated congenital heart diseases

A and B, Helical CT angiography obtained by using conventional 3D reconstruction (A) and 3D color coding (B). C, Separation of the systemic and pulmonary arteries (red), pulmonary veins (blue), and systemic veins (green) on a tomographic image of the same patient. LSVC, Left superior vena cava; LPA, left pulmonary artery; PDA, patent ductus arteriosus; PV, pulmonary vein; VV, vertical vein; dAo, descending aorta.

A and B, A neonate with HLHS from the anterior (A) and right posterior (B) view. Arrows indicate ascending aorta. C and D, An infant with supracardiac-type TAPVD of the anterior (C) and posterior (D) views. Arrows indicate stenosis of the vertical vein. SVC, Superior vena cava; Ao, aorta; PA, pulmonary artery; PDA, patent ductus arteriosus; dAo, descending aorta; rPV, right pulmonary vein; Ao, aorta; IPV, left pulmonary vein; INV, innominate vein.

A and B, An infant with PA with VSD accompanying MAPCA from the posterior (A) and right posterolateral view (B). Arrows indicate aortopulmonary collateral arteries. C-E, Helical CT bronchograms (C, anterior view; D and E, transverse section). The left upper bronchus (arrow in C) was compressed by one of the major collateral arteries (arrows in D and E). dAo, Descending aorta; CPV, common pulmonary vein.
