2. Figure 1
Selected cross-sectional images of thoracic CT scans from two women with COPD related to biomass exposure (A) and to cigarette smoke (B). A, A 66-year-old female subject with an FEV1 of 28% predicted (lifetime nonsmoker) had COPD related to biomass exposure. The arrow indicates an airway with a thick wall suggestive of airway wall remodeling. B, A 70-year-old female subject with an FEV1 of 46% predicted had a 24-pack-year smoking history. The asterisk indicates paucity of lung markings suggestive of emphysema.
