This study is looking at young adults who are already part of the American Lung Association Lung Health Cohort. Researchers will use a special type of MRI called Hyperpolarized 129Xe MRI to look at your lungs. This involves inhaling a gas called hyperpolarized 129Xe, which helps the MRI machine see your lungs better. The goal is to understand lung structure and function, and to identify early signs of lung problems that could lead to chronic lung disease. You can join if you are 25 to 35 years old, have had a CT scan for the Lung Health Cohort study within the last two years, and don't have certain implanted medical devices like pacemakers. The main thing they will measure is something called the Xe-MRI Apparent Diffusion Coefficient at your first imaging visit. The current recruitment status is unclear.

Study design

This is an observational study, meaning researchers will observe participants without providing a specific treatment. It plans to enroll 260 healthy individuals.

What's involved

You would undergo Hyperpolarized 129Xe MRI imaging. You must have completed a CT scan for the Lung Health Cohort study within two years of the MRI date.

Compensation

Not stated in the trial record.

Follow-up

The primary measurement is taken at the baseline imaging timepoint. Further follow-up is not specified.
