Official title
The Effect of Airway Clearance Therapy on Hyperpolarized 129Xenon MRI Compared With Lung Clearance Index and Spirometry in Cystic Fibrosis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is an observational cohort study building on an existing protocol at our institution recruiting CF patients who are 6-21 years old with one or two copies of the F508del CFTR mutation. That existing protocol seeks to enroll a total of 38 subjects; it includes three to four (three scheduled, with a fourth optional) study visits, with spirometry, LCI, UTE MRI, and 129Xe MRI being performed at each visit. This present study will utilize existing study visits for the NHLBI study, with a sub-set of 20 subjects opting-in to have all of the procedures performed twice, with an intervening ACT, during one of their study visits.
