Using hyperpolarized xenon MRI to assess lung function in adults
Use of Hyperpolarized 129Xe MR Lung Imaging in Adults for Calibration
This study is testing if a special type of MRI using xenon gas can help us see how well the lungs are working in healthy adults.

What this trial studies
This study evaluates the effectiveness of hyperpolarized 129Xe MRI for assessing lung function in healthy adults. Participants will inhale hyperpolarized xenon gas and undergo MRI scans to capture detailed images of lung function. The imaging sessions will occur on a single day, with follow-up assessments scheduled one day and 30 days post-imaging. The goal is to optimize imaging techniques for future applications in respiratory disorders.
Who should consider this trial
Good fit: Ideal candidates are healthy adults aged 18 and older who can hold their breath for up to 16 seconds.
Not a fit: Patients with a history of heart defects, uncontrolled asthma, or respiratory infections may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could enhance the diagnosis and monitoring of respiratory disorders through improved imaging techniques.
How similar studies have performed: While the use of hyperpolarized xenon MRI is a novel approach, similar imaging techniques have shown promise in assessing lung function in other studies.
