Summary

This study looks at how mucus plugs block airways in people with severe asthma. Using special xenon MRI scans, researchers will measure how these plugs affect breathing and gas exchange. Five adults with severe asthma will be scanned before and after starting biologic therapy to see if treatment helps clear the blockages.
