Imaging considerations in tetralogy of Fallot: A comprehensive review

Figure 5 Computed tomography images. A-C: Axial (A and B) and sagittal reformatted images (C) of computed tomography angiography in a child with cyanosis, showing infundibular pulmonary stenosis (block arrow in A), right ventricular hypertrophy (asterisk in B), perimembranous ventricular septal defect (block arrow in B) with 50% aortic override (asterisk in C) consistent with classical tetralogy of Fallot; D-F: Axial (D and E) images showing stenosis at the origin of the left pulmonary artery (arrow). The right pulmonary artery was normal (asterisk); F: Three-dimensional volume rendered image showing the left pulmonary artery stenosis (arrow).
