Smart scans aim to spare healthy lung during cancer radiation

This study tests whether using a lung perfusion PET/CT scan to guide radiation planning can reduce lung injury compared to standard anatomical planning. About 418 adults with lung tumors receiving stereotactic body radiotherapy (SBRT) will be randomly assigned to one of the two planning methods. The goal is to see if the personalized approach lowers the chance of moderate to severe lung side effects within a year after treatment.
