New MRI technique aims to protect lungs during cancer radiation

This early-stage study tested whether a special type of MRI scan, which uses inhaled xenon gas to map how well the lungs are working, could help doctors plan radiation therapy for lung cancer. The goal was to see if this detailed map could help direct radiation doses away from the healthiest parts of the lung, potentially reducing side effects like lung inflammation. The study was small and focused first on ensuring the scanning process was safe for patients with reduced lung function.
