Breathing in a special gas reveals hidden lung damage in transplant patients

This study used a special MRI technique with a harmless gas called hyperpolarized xenon-129 to take detailed pictures of lung function in people who had a lung transplant. The goal was to see if this scan could detect early signs of chronic lung allograft dysfunction (CLAD), a common complication after transplant. Researchers compared transplant patients, healthy volunteers, and people with COPD to understand how the gas moves through the lungs and where problems might be.
