Can new scans catch lung transplant failure before It's too late?

This study tests whether advanced imaging techniques, including oxygen-enhanced MRI and hyperpolarized xenon MRI, can detect chronic lung allograft dysfunction (CLAD) earlier than standard lung function tests. CLAD is a common complication after lung transplantation that can lead to organ failure. The study will compare these imaging methods with spirometry and CT scans in lung transplant recipients and healthy volunteers. The goal is to see if these scans can provide a more accurate and earlier diagnosis, which could help guide treatment and improve outcomes.
