This study is using the most advanced methods for measuring lung function including 2 tests called hyperpolarised gas magnetic resonance imaging (HP MRI) and multiple breath washout (MBW), to better understand changes in the lungs over time.\n\nHP MRI involves taking pictures of the air in your lungs after breathing in a harmless gas (xenon). MBW is a breathing test used to calculate something called the lung clearance index (LCI).\n\nBy measuring these tests on the same day, alongside standard lung function tests, we aim to understand lung function in greater detail than ever before.",[66],"Cystic Fibrosis (CF)","2026-04-23",{"date":69,"type":70},"2026-04-29","ACTUAL",{"date":72,"type":70},"2024-02-21",{"date":74,"type":62},"2029-06-30",{"name":5,"class":6},1]
