Radiation oncologists and radiologists have a unique and mutually dependent relationship. Radiation oncologists rely on diagnostic imaging to locate the tumor and define the treatment target volume, evaluation of response to therapy, and follow-up. Accurate interpretation of post-treatment imaging requires diagnostic radiologists to have a basic understanding of radiation treatment planning and delivery. There are various radiation treatment modalities such as 3D conformal radiation therapy, intensity modulated radiation therapy and stereotactic radiosurgery as well as different radiation modalities such as photons and protons that can be used for treatment. All of these have subtle differences in how the treatment is planned and how the imaging findings might be affected. This paper provides an overview of the basic principles of radiation oncology, different radiation treatment modalities, how radiation therapy is planned and delivered, how knowledge of this process can help interpretation of images, and how the radiologist can contribute to this process.
放射肿瘤学家和放射科医生有着独特且相互依存的关系。放射肿瘤学家依靠诊断成像来定位肿瘤、确定治疗靶区、评估治疗反应以及进行随访。准确解读治疗后的影像需要诊断放射科医生对放射治疗计划和实施有基本的了解。有多种放射治疗方式,如三维适形放射治疗、调强放射治疗和立体定向放射外科,以及不同的放射模式,如光子和质子,可用于治疗。所有这些在治疗计划方式以及影像表现可能如何受到影响方面都存在细微差异。本文概述了放射肿瘤学的基本原理、不同的放射治疗方式、放射治疗的计划和实施方式、对这一过程的了解如何有助于影像解读,以及放射科医生如何为这一过程做出贡献。
