Overview
This Symposium was proposed by the MR in Radiation Therapy study group. This symposium will build upon the recent success of the 2020 ISMRM MR-guided radiotherapy plenary session. The area of MR-guided radiotherapy is where MR imaging has a direct and profound impact on the patient’s treatment outcome. However, numerous challenges still exist particularly in the radiotherapy of the body region, where developments in MRI technologies are in urgent need. The aim of the session is to continue raising interests among ISMRM communities in the emerging field of MR-guided radiotherapy and to foster collaborations between the ISMRM and AAPM societies. We have invited and confirmed five prominent investigators with extensive experiences in both MRI and radiotherapy in areas of imaging acceleration, motion management, and tumor response to treatment. These research areas highlight the most critical aspects of radiotherapy that will benefit from advanced MRI techniques and data analysis methods. In the session, each speaker will give a lecture of 20 min with Q&A. The session concludes with an interactive panel discussion, led by the organizers, about the MR methods needed to advance the field. The MRI-guided RT symposium will be a welcome addition to the meeting program. Apart from introducing new people to this exciting new field, it will also provide a common forum for people already working in radiotherapy to meet and share ideas.

Target Audience
Researchers and clinicians interested in the general topic of using MRI for all radiotherapy applications.

Educational Objectives
As a result of attending this course, participants should be able to:
Upon completion of this course, participants should be able to: - Explain the current state of the art in tumor motion management and real-time imaging guidance for radiotherapy treatmen; - Describe the latest advances in probing tumor diffusion, perfusion, and tissue oxygenation in the setting of radiotherap; - List the clinical needs to enable true adaptive radiotherapy and precision RT treatment; and - Recognize research opportunities for MR scientists and physicists to get involved in this exciting area.
