We will optimise and implement 3D MR spirometry in clinical sites at standard fields (1.5 T and 3 T) to produce an unprecedentedly large database on adult and children healthy volunteers and patients covering major lung chronic pathologies (asthma, chronic obstructive pulmonary diseases, bronchiolitis obliterans syndrome, primary immunodeficiency, bronchopulmonary dysplasia, cystic fibrosis) and therapy follow-ups (lung transplantation, biotherapy, reversibility).
