Magnetic resonance (MR) imaging has advanced to offer high intrinsic contrasts, biologically‐relevant signals, rapid volumetric imaging, and compatibility with intervention. These advances are strikingly compatible with the current efforts in advancing the precision and accuracy of radiation therapy. The growing drive towards conformal, biologically targeted RT will draw MR imaging data and MR technology into radiation oncology practice. Simulation and planning in RT now routinely draws on MR for target and normal tissue segmentation. This includes the growing trend toward installing dedicated MR systems in the radiation oncology department. Furthermore, there have been numerous reports on the development of integrated MR‐guided RT units for increased precision and accuracy in RT. The rationale for these developments and the technical challenges associated with successful execution will be discussed.
