Magnetic resonance imaging (MRI) is increasingly being used in radiation therapy, and integration of MRI into brachytherapy in particular is becoming more common. We present here a systematic review of the basic physics and technical aspects of incorporating MRI into prostate brachytherapy. Terminology and MRI system components are reviewed along with typical work flows in prostate high-dose-rate and low-dose-rate brachytherapy. In general, the brachytherapy workflow consists of five key components: diagnosis, implantation, treatment planning (scan + plan), implant verification, and delivery. MRI integration is discussed for diagnosis; treatment planning; and MRI-guided brachytherapy implants, in which MRI is used to guide the physical insertion of the brachytherapy applicator or needles. Considerations and challenges for establishing an MRI brachytherapy program are also discussed.
磁共振成像（MRI）在放射治疗中的应用越来越广泛，尤其是将MRI整合到近距离放射治疗中变得越来越普遍。我们在此对将MRI纳入前列腺近距离放射治疗的基本物理和技术方面进行系统综述。回顾了术语和MRI系统组件，以及前列腺高剂量率和低剂量率近距离放射治疗的典型工作流程。一般来说，近距离放射治疗工作流程包括五个关键组成部分：诊断、植入、治疗计划（扫描+计划）、植入验证和治疗实施。讨论了MRI在诊断、治疗计划以及MRI引导的近距离放射治疗植入中的整合应用，其中MRI用于引导近距离放射治疗施源器或针的物理插入。还讨论了建立MRI近距离放射治疗项目的注意事项和挑战。
