The clinical use of MR-guided radiotherapy (MRgRT) has been feasible for the last three years using a low-field 0.35T Cobalt IMRT system. This new technology offers real-time image guidance throughout the course of treatment delivery which is a paradigm shift from current image-guided radiotherapy approach of "peak and shoot". Early clinical experience suggest that use of MRgRT, particularly utilizing on-table adaptive radiotherapy with daily assessment of plan quality and optimization may translate to a clinical benefit in locally advanced pancreatic cancer, liver tumors and oligometastatic disease. However, there are a number of challenges in the early adoption of MRgRT including technical aspects like image quality, and minimal automation, as well as clinical challenges such as lack of a defined process of care and its high resource requirements in order to implement it in a routine radiation oncology clinic. This session serves to discuss current and future strategies for MRgRT as well as identified areas of needed technical and clinical advancements in order to realize its potential in a routine radiation oncology clinic including incorporating patient-reported outcome measures and quality of life assessments in future studies to prove the value of MR-guided radiation therapy.
