This article covers positron emission tomography-computed tomography (PET-CT) scan protocols for radiation therapy planning purposes and therapy response assessment. For radiation therapy planning PET-CT scans, protocols used will depend on the intended use of the PET-CT images in the radiation therapy planning. In general scans are performed on a flat radiation therapy pallet with the patient in the treatment position or closely approximating the treatment position. PET-CT protocols used in radiation therapy planning are typically otherwise very similar to diagnostic protocols. An important component in PET-CT imaging performed for therapy monitoring and assessment is consistency in patient preparation, image acquisition, and imaging processing of the baseline scan and subsequent therapy assessment scans.
本文涵盖了用于放射治疗计划制定及治疗反应评估的正电子发射断层扫描-计算机断层扫描(PET-CT)扫描方案。对于放射治疗计划PET-CT扫描,所采用的方案将取决于PET-CT图像在放射治疗计划中的预期用途。一般来说,扫描是在平板放射治疗托盘上进行的,患者处于治疗体位或非常接近治疗体位。放射治疗计划中使用的PET-CT方案通常在其他方面与诊断方案非常相似。在为治疗监测和评估而进行的PET-CT成像中,一个重要组成部分是患者准备、图像采集以及基线扫描和后续治疗评估扫描的成像处理的一致性。
