Combined helium‐3/proton magnetic resonance imaging measurement of ventilated lung volumes in smokers compared to never‐smokers

To use a combination of helium‐3 (3‐He) magnetic resonance imaging (MRI) and proton single‐shot fast spin echo (SSFSE) to compare ventilated lung volumes in groups of “healthy” smokers, smokers diagnosed with moderate chronic obstructive pulmonary disease (COPD), and never‐smokers.
