Abstract
Objectives To investigate the relationship between small pulmonary vessels and extent of emphysema on CT in individual lungs with chronic obstructive pulmonary disease (COPD). Methods Forty-nine patients were included. The percentage of cross-sectional area of vessels < 5 mm2 (%CSA < 5) and extent of emphysema were assessed. Results Less than half of the COPD patients demonstrated an inverse correlation between %CSA < 5 and percentage of low attenuation area (LAA%). In the remaining patients, %CSA < 5 was homogeneously distributed. Conclusion Not all patients with COPD demonstrated an inverse correlation of the distributions between %CSA < 5 and LAA% in individual lungs.
