Read our COPD research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is following people with COPD or bronchiectasis to see how their lungs change over time. Researchers are using two special types of MRI scans—one using helium-3 and one using xenon-129—along with standard breathing tests and CT scans to get a detailed picture of lung function and structure.
Doctors want to better understand how COPD and bronchiectasis develop and progress so they can find better ways to diagnose and treat these lung diseases earlier. These new MRI imaging techniques may help detect changes that standard tests miss.
You would visit the research clinic up to 8 times over 2–3 years. At each visit (lasting about 2–2.5 hours), you'll perform breathing tests like spirometry and oscillometry, walk for 6 minutes while researchers measure your oxygen and symptoms, complete questionnaires about your lung health, and undergo MRI and CT scans of your chest. Researchers will provide transportation by wheelchair to help you stay comfortable between tests.
