COPD cores show clear emphysema a. Surface density is significantly lower in cores from COPD explant lungs compared to cores from unused donor lungs. Representative images of a μCT from a core from an unused donor lung (b) and a COPD explant lung (c). Emphysema is clearly present in the core from the COPD explant lung.
