a, b Different rendering software highlights different anatomical structures, as illustrated in these images of a 2-month-old child with congenital emphysema. a Using the MaxIP application, the parenchymal vasculature is clearly seen in the coronal and axial images (i and ii), even within the affected lobes. b Coronal (iii) and axial (iv) MinIP reformatted images show the central airway together with segmental air trapping, easily visualised within both lower lobes.
