Breath-hold MRI study to test imaging reliability
This study uses a special MRI gas (xenon-129) and scanner software to check how reliably images can be repeated. You may be able to help researchers improve MRI technology, as long as you can safely do the breathing and MRI scanning steps.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You can hold your breath for up to 16 seconds
- Your body mass index (BMI) is between 18 and 40
- You have no major health problems based on your medical history
- You have smoked less than 1 pack per year in total
- Your oxygen level is at least 90% while lying flat
- You can do breathing tests like spirometry or plethysmography

This research study uses a special type of MRI scan with xenon gas to take detailed pictures of your lungs and how they work. The goal is to develop better ways to evaluate lung function and potentially help diagnose or monitor lung diseases.
This study tests whether a special MRI scan using xenon gas can be done safely and provide useful information in people with chronic lung conditions. You may be able to take part if your breathing tests and oxygen levels are adequate and you can complete the MRI safely.
This study repeatedly takes special MRI pictures of the lungs using helium-3 and xenon-129 gas to track how lung function changes over time. It may help researchers better understand lung disease in people who have COPD or bronchiectasis, or a long smoking history.
This trial uses a special breathing MRI (you breathe a gas mixture) to measure how well your lungs work. It studies healthy kids and people with lung conditions like cystic fibrosis or asthma, and it may help researchers better understand lung function and flare-ups.
This study uses a special MRI with a gas called perfluoropropane to create detailed images of the lungs. It is for healthy volunteers to see how well this imaging method works.
This study uses MRI pictures to learn how asthma affects breathing and lung function. If you have asthma and can do breathing tests, you may be asked to take part to help researchers understand asthma better.
