Abstract
Purpose To examine the clinical advantages of magnetic resonance-guided linear accelerator (MR-Linac) technology in radiation therapy, with a focus on treatment accuracy, adaptive planning, and patient outcomes.
Method A literature review was conducted using peer-reviewed articles identified through The University of Texas MD Anderson Cancer Center Research Medical Library. Studies published between 2022 and 2026 were included if they addressed the clinical advantages of MR-Linac technology. Findings were synthesized using thematic analysis.
Results Three primary themes emerged: (a) superior soft-tissue visualization improved tumor delineation and treatment accuracy; (b) daily adaptive treatment planning and real-time tumor tracking enhanced precision by accounting for anatomical changes during therapy; and (c) reduced radiation exposure to surrounding healthy tissues decreased treatment-related toxicity while supporting improved clinical outcomes.
Discussion The reviewed evidence demonstrates that MR-Linac technology represents a significant advancement in radiation oncology by integrating high-quality magnetic resonance imaging with real-time radiation delivery. Enhanced visualization and adaptive treatment planning enable more precise tumor targeting while minimizing radiation exposure to surrounding healthy tissues. Although longer treatment sessions, patient eligibility restrictions, and equipment costs remain barriers to widespread implementation, the reported clinical benefits support continued adoption and further evaluation of MR-Linac technology.
Conclusion MR-Linac technology improves treatment precision through superior soft-tissue visualization, adaptive treatment planning, and reduced toxicity to healthy tissues. Continued research is needed to evaluate long-term outcomes and further establish its role as a standard approach in radiation therapy.
