Small Airways on CT

Normal CT scan of the Terminal Bronchioles
The bronchiole subtending the posterior segment of the right lower lobe (a) measured 3.2mm (red) just before its division. Image b, shows the next division and these bronchioles, measured 2.3mms( b – red). Thereafter the airways, likely terminal bronchioles, are barely seen alongside their arteriole (teal rings) likely measuring in the 1.7-2mms range and are within 1cms of the lung margin.
