Abstract Magnetic resonance imaging (MRI) is becoming increasingly important in precision radiotherapy owing to its excellent soft‐tissue contrast and versatile scan options. Many recent advances MRI have been shown be promising for MRI‐guided improved treatment outcomes. This paper summarizes these into six sections: simulators, MRI‐linear accelerator hybrid machines, MRI‐only workflow, four‐dimensional MRI, MRI‐based radiomics, magnetic fingerprinting. These techniques can implemented before, during, or after various applications, such as tumor delineation, motion management, adaptation, clinical decision making. For each of techniques, this describes technical details discusses benefits challenges.
