Stereotactic body radiotherapy (SBRT) is a relatively new technique that enables delivery of high doses of radiation to malignancies throughout the body with a higher degree of precision than conventional radiation modalities. PET and computed tomography are rapidly being adopted for the evaluation of patients with cancer, and its role in conjunction with SBRT is under active investigation. This article reviews the literature regarding the utility of PET and computed tomography in treatment planning, follow-up imaging, relationship with clinical outcomes, and other topics in patients treated with SBRT. These questions are investigated for cancers of the lung, head and neck, pancreas and liver. A brief overview of various commercially available SBRT treatment systems is also included.
立体定向体部放射治疗（SBRT）是一种相对较新的技术，能够以比传统放射治疗方式更高的精度将高剂量的辐射输送到全身的恶性肿瘤中。正电子发射断层扫描（PET）和计算机断层扫描（CT）正在迅速被用于癌症患者的评估，其与 SBRT 联合应用的作用正在积极研究中。本文综述了关于在治疗计划、随访成像、与临床结果的关系以及 SBRT 治疗患者的其他方面中使用 PET 和 CT 的文献。这些问题是针对肺癌、头颈部癌、胰腺癌和肝癌进行调查的。还简要概述了各种市售的 SBRT 治疗系统。
