The role of radiotherapy in the management of primary and metastatic liver malignancies has expanded in recent years due to advances such as IGRT and SBRT. MRI-guided radiotherapy (MRgRT) has arisen as an excellent option for the management of hepatocellular carcinoma, cholangiocarcinoma, and liver metastases due to the ability to combine improved hepatic imaging with conformal treatment planning paradigms like adaptive radiotherapy and advanced motion management techniques. Herein we review the data for MRgRT for liver malignancies, as well as describe workflow and technical considerations for the 2 commercially available MRgRT delivery platforms.

近年来，由于 IGRT放疗在原发性和转移性肝脏恶性肿瘤治疗中的作用不断扩大>肝转移瘤的绝佳选择，因为它能够结合改进的治疗方法肝脏成像与适形治疗计划范例，如自适应放射治疗和先进的运动管理技术。在此，我们回顾了肝脏恶性肿瘤 MRgRT 的数据，并描述了 2 个市售 MRgRT 输送平台的工作流程和技术注意事项。胆管癌和 和 SBRT。 MRI 引导放疗 (MRgRT) 已成为治疗肝细胞癌、
