Study Details

Brief summary:

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.

Interventions and Outcome Measures

Arms

CF and Non-CF Bronchiectasis

In the first arm (Aims 1 \& 2) Up to 50 subjects will be recruited-approximately 25 with normal FEV1 (>85% predicted) and 25 with mild to moderate disease. All subjects will be asked to undergo longitudinal (i.e., approximately annually) 129Xe and UTE MRI, spirometry, and lung clearance index (LCI) measurement.

Healthy Subjects

Up to 50 age and sex matched control subjects (i.e., subjects with no known cardiopulmonary disorders) may also be recruited to provide a reference data set from healthy subjects for comparison.

Interventions

Xenon

Subjects will be scanned on a commercial 3T whole-body MRI scanner equipped with high-performance gradient systems. Natural isotopic abundance or isotopically-enriched xenon gas (\~86% 129Xe, Linde Inc.) will be used for all studies. Subjects will be positioned supine in the scanner with a 129Xe RF coil around their chests. Using conventional proton MRI and a breath-hold acquisition, "scout" images will be obtained to localize the subject for subsequent 129Xe acquisitions. 129Xe images will be acquired using the same breath-hold maneuver and a pulse sequence, covering the entire lung (acquisition time <10 s, approximately 3-mm in-plane resolution, 15-mm slice thickness or less). Additional scans (sequences) may be performed. A maximum of 4 doses of 129Xe will be given throughout the study following the calibration dose.

Primary outcome measure

  • Correlation of ventilated volume predictions obtained with 129Xe MRI vs 1H MRI [ Time Frame: Annually for 5 years ]
