- •
HRCT measurements are related with different exercise-induced ventilatory responses.
- •
Low attenuation areas (LAA) predicts Δ rest-to-peak IC/TLC and VE/VCO2slope.
- •
Wall area (WA) is inversely correlated with VE/VCO2 slope.
- •
The value of LAA 9.3% identify the presence of dynamic hyperinflation.
