Panels A and C provide a coronal view of the lungs of a smoker with normal lung function (Panel A) and one with moderate emphysema (Panel C). Panels B and D provide volumetric reconstructions of the left lung pulmonary vasculature from a left mid axillary view. Vessels are color coded by diameter. Notice the loss of vasculature and thinning of the vessels in regions most affected by emphysema.
