Analysis of CT images to assess chronic obstructive pulmonary disease (COPD) phenotype

Analysis of CT scans could be useful for assessing COPD phenotype. An image analysis technique called parametric response mapping was used to assess pulmonary CT scans from 194 patients with COPD. The analysis technique was used to determine disease severity and suggested functional small airways disease precedes emphysema in patients with COPD. Next steps include developing a software package to carry out parametric response map analysis of lung CT scans.
