MR-guided radiotherapy is a treatment approach that combines the advantages of magnetic resonance imaging (MRI) with the precision of radiation therapy. This practical review provides an overview of the current state-of-the-art of MR-guided radiotherapy for rectal cancer, including its technical aspects, clinical outcomes, and existing limitations. Even though some studies have demonstrated the feasibility and safety of this treatment modality, challenges remain in terms of patient selection, treatment planning optimization, and long-term follow-up. Despite these issues, MR-guided radiotherapy shows promise as a potentially valuable rectal cancer treatment approach.

磁共振引导放射治疗是一种结合了磁共振成像（MRI）优点和放射治疗精度的治疗方法。这篇实用综述概述了当前 MR 引导直肠癌放疗的最新技术，包括其技术方面、临床结果和现有局限性。尽管一些研究证明了这种治疗方式的可行性和安全性，但在患者选择、治疗计划优化和长期随访方面仍然存在挑战。尽管存在这些问题，磁共振引导放疗仍显示出作为一种潜在有价值的直肠癌治疗方法的前景。
