RecruitingPhase 2Drug trialUsing Xe MRI to Guide Radiation Therapy for Lung CancerThe purpose of this research study is to explore using MRI scans with xenon to better image lung function, how lung function changes after radiation therapy, and to guide radiation therapy away from parts of the lung that have good function. This project is foundational to performing additional studies to establish if novel MRI imaging can serve as a guidance tool for lung cancer radiation treatment.
