Is this trial a fit for you?

Likely a good fit

Ideal candidates include lung transplant patients who are at least six months post-transplant and have a history of bilateral lung transplant, as well as healthy individuals aged 18-80.

Probably not a fit

Patients who are current smokers or have significant lung infections or allograft rejection may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the effectiveness of oxygen-enhanced MRI (OE-MRI) and hyperpolarized gas MRI techniques, alongside iodinated contrast CT scans, to better understand chronic lung allograft dysfunction (CLAD) in lung transplant patients. It will involve healthy subjects and lung transplant recipients, assessing lung ventilation under different oxygen levels. The findings could pave the way for using novel MRI imaging as a diagnostic tool for CLAD, enhancing patient management post-transplant.

Why it matters

Potential benefit: If successful, this study could provide a non-invasive diagnostic tool for early detection of chronic lung allograft dysfunction in lung transplant patients.

How similar studies have gone: While the use of advanced MRI techniques in lung imaging is promising, this specific approach to diagnosing CLAD is relatively novel and has not been extensively tested in prior studies.
