The Investigator's central hypothesis is that image-based markers can forecast pathophysiology prior to spirometric changes.", 'detailedDescription': "Specific Aim 1: Validate functional imaging markers in CF patients with normal spirometry but abnormal ventilation. The Investigators hypothesize imaging phenotype can predict lung function decline, even in CF patients with normal spirometry. The Investigators will test this hypothesis by performing annual HP 129Xe ventilation MRI in a cohort of CF patients of which a subset has normal FEV1 (≥85% predicted) at baseline.\n\nSpecific Aim 2: Determine the sensitivity and specificity of early structural remodeling in CF lung disease. The Investigator's preliminary studies show that imaging markers of structural lung remodeling can be measured via radiation-free MRI (as opposed to x-ray CT). We assess the sensitivity to identify subjects with irreversible remodeling by performing serial ultra-short UTE MRI.\n\nIn 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. If possible, studies will be coordinated with clinical visits to maximize recruitment and retention. 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.\n\nHealthy adults, including CCHMC employees) and children \\>5 years old may be recruited as needed for MRI sequence development and validation.\n\nIn the second arm (Aim 3), 50 CF patients with bronchiectasis and 50 with non-CF bronchiectasis will be recruited from patients already undergoing clinical bronchoscopies. Before bronchoscopy, subjects will undergo UTE. BAL will be obtained from radiologically normal areas and regions with abnormalities. (Note, image-guided sampling from multiple sites is routine practice at CCHMC in patients with CF and non-CF bronchiectasis. As such, the proposed studies will not alter the sampling pattern in a clinically significant way or increase procedure time, and will thus add no patient risk.) Clinical BAL will be collected from these regions, and small aliquots (\\~500 µL) will be stored separately for proteomics. The remaining fluid will be pooled and submitted for routine clinical testing, with \\~500 µL reserved for pooled proteomics. The Investigators will recruit \\~10 subjects/yr from both CF and non-CF groups, who will be followed annually with UTE and proteomic analysis that will be collected under Dr. Ziady's companion protocol, titled Proteomic biomarkers of CF disease and non-CF bronchiectasis to measure prognostic markers of disease-in particular of persistent bronchiectasis. For all subjects, clinical data (e.g., age, gender, CF genotype, microbiology, therapies-including CFTR modulators-and exacerbation frequency) will be captured in a REDcap database."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'maximumAge': '100 Years', 'minimumAge': '5 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'CF and Non-CF Bronchiectasis patients', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* CF Patients: Diagnosis of CF based on sweat chloride \\>60 mMol/l\n* Presence of two disease causing CFTR mutations, or end organ manifestations of disease.\n* Age minimum 5 years.\n* Care provided by the CCHMC CF Care Center or other regional CF Care Centers if required to achieve recruitment goals.\n\nExclusion Criteria:\n\n* Patients meeting standard MRI exclusions criteria (non-MRI-compatible metal implants, claustrophobia, etc.)\n* Pregnancy or lactation.\n\nInclusion Criteria of Healthy Subjects:\n\n* Subjects 5 years of age and older with no known history of cardiopulmonary disease.\n\nExclusion Criteria of Healthy Subjects:\n\n* Patients meeting standard MRI exclusions criteria (non-MRI-compatible metal implants, claustrophobia, etc.)\n* Pregnancy or lactation.'}, 'identificationModule': {'nctId': 'NCT04793867', 'briefTitle': 'Regional Phenotyping of CF and Non-CF Bronchiectasis', 'organization': {'class': 'OTHER', 'fullName': "Children's Hospital Medical Center, Cincinnati"}, 'officialTitle': 'Regional Phenotyping of Cystic Fibrosis Lung Disease and Non-CF Bronchiectasis', 'orgStudyIdInfo': {'id': '2020-0814'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'CF and Non-CF Bronchiectasis', 'description': '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.
