Imaging considerations in tetralogy of Fallot: A comprehensive review

Figure 6 Computed tomography images. A-D: Oblique axial maximum intensity projection images and volume rendered image showing supravalvular main pulmonary artery (orange arrow) and right pulmonary artery (blue arrow) stenosis in a known case of TOF (A); coronal reformat image showing the main pulmonary artery stenosis (arrow) (B); coronal reformat image showing right pulmonary artery stenosis (blue arrow) (C); three-dimensional volume rendered image showing supravalvular main pulmonary artery stenosis (arrow) (D); E-H: Axial computed tomography angiography images showing pulmonary arterial anomalies in different patients of tetralogy of Fallot. E: Pulmonary atresia (block arrow) with reformed, confluent pulmonary arteries (asterisk); F: Pulmonary atresia with non-confluent, reformed pulmonary arteries (block arrow); G: Pulmonary atresia with absent main and branch pulmonary arteries (block arrow); H: Aneurysmal dilatation of the main pulmonary artery (block arrow) due to absent pulmonary valve.
