Coronal reconstruction from a non-contrast high resolution computed tomogram (CT) of the thorax with axial sections marked (a) at the level of the top of the aortic arch, (b) at the carina, (c) 1 cm below the carina, (d) at the level of the midpoint of the right pulmonary vein, and (e) 2 cm above the dome of the right hemi-diaphragm. The corresponding axial slices are shown (a-e). Representative measurements of airway wall (W) and diameter (D) are shown, taken from slice (e), (i) and (ii) respectively.
