Non-CF Bronchiectasis

In this study, xenon MRI will be used to evaluate regional functional consequences of mucus plugs in the lungs of patients with muco-obstructive pulmonary disease. Mucus plugs will be identified using CT imaging, and xenon MRI will be used to evaluate ventilation and gas exchange impairments in regions of the lungs corresponding to the airways downstream of mucus plugs.

The Investigators propose to study pediatric subjects who are diagnosed with cystic fibrosis (CF) and patients with non-CF bronchiectasis, with the goal of developing markers of CF lung disease severity, progression, and therapy response. The Investigator's central hypothesis is that image-based markers can forecast pathophysiology prior to spirometric changes.

The Bronchiectasis Research Registry is a consolidated database of non-cystic fibrosis (non-CF) Bronchiectasis and Nontuberculosis Mycobacteria (NTM) patients from multiple clinical institutions.
