Computed tomography images indicating the calculation of LAR. At the level where the brachiocephalic artery crosses the trachea, LAR is calculated by dividing the long axis length of the trachea by the short axis length. a Neonate without tracheal collapse. b Neonate with tracheal collapse complicated by esophageal atresia.
