Correlation between particle DF and DL,CO for COPD subjects. Correlation between DL,CO and particle deposition for emphysematous subjects (n = 12). The included subjects were confirmed to have emphysema by visual CT evaluation and graded to have mild (n = 2), moderate (n = 2) and severe (n = 8) emphysema. The visual grading is indicated by colour intensity (white = mild, light blue = moderate, dark blue = severe). Four subjects were omitted from the analysis based on a DL,CO > 95% of predicted, or missing data. Of these one had no emphysema and one was graded as having mild emphysema but 97% of predicted DL,CO, CT data was missing for one subject and DL,CO was missing for one subject
