Valutazione del trattamento del modulatore CFTR nella fibrosi cistica polmonare utilizzando una nuova risonanza magnetica strutturale e funzionale

Healthy participants without lung disease

Participants with stable cystic fibrosis

Participants with cystic fibrosis, anticipated to receive treatment with CFTR-modulator therapy. Please note: treatment is determined by your physician as part of your normal therapy plan.

Participants with CF who are between 4-8 years old and are starting triple combination modulator therapy using the rapid lung and abdominal imaging methods.

Establish the interscan reproducibility of fractional ventilation maps and 1H MRI over three and up to six visits in healthy volunteers and in patients with stable CF lung disease and compare to conventional spirometry and LCI.

Correlate changes in lung structure and function detected by MRI imaging with clinical outcomes including FEV1 rate of decline, frequency of pulmonary exacerbations, days of IV antibiotics and hospital days to treat pulmonary exacerbation and change in health-related quality of life measures (CFQ-R scores and CF-QUEST) in the setting of patients with stable CF lung disease and those receiving CFTR-modulator therapy.

Assess responsiveness of MRI to treatment effects over three and up to six visits visits in CF patients receiving CFTR-modulator therapy and compare to conventional breathing tests

Extension of above objectives originally only explored in children ages 8-18 years old, to younger cohort of CF participants ages 4-8 years old at baseline prior to initiation of CFTR modulator therapy, as well as at 12 and 24 months after therapy initiation.
