Fig. 3a, b
A 12-year-girl with cystic fibrosis. a The AP radiograph shows mild to moderate general changes of cystic fibrosis; with increased linear markings and discrete nodular opacities (arrowheads) in the periphery of both lungs. Bronchiectases are suspected in the upper parts of both hilar regions (white arrows). b A tomosynthesis section shows the CF changes in more detail. There is general bronchial wall thickening. Cylindrical bronchiectasis (white arrows) and small mucus plugs (arrowheads), in a tree-in-bud pattern on the right side, are also clearly depicted. Artefacts from a central venous access device can be seen in the right upper quadrant (black arrow)
