a Posterior oblique VRT image of a 2-month-old child shows a right-sided aortic arch with mirror branching pattern demonstrated. Scanning parameters: 80 kV, 62 mAs, 0.70 CTDIvol, 8 DLP. b Axial MaxIP image (i) of a 2-year-old child shows a right dominant aortic arch with a Kommerell’s diverticulum and an aberrant left subclavian artery seen on the VRT image (ii). A patent arterial duct connects to the left pulmonary artery, completing a vascular ring around the trachea that is mildly compressed due to a dilated oesophagus seen in (i). Scanning parameters: 80 kV, 33 eff mAs, 150 ref mAs, 1.15 CTDIvol, 20 DLP
