背景:[18F]在全身PET/CT(TBPET/CT)扫描仪上进行FDG成像,随着灵敏度的提高,为癌症诊断提供了新的潜力,分期,和放射治疗计划。这一共识为临床实践提供了协议,目的是为肿瘤[18F]FDGTBPET/CT成像中的全身扫描仪的未来研究铺平道路。
方法:根据已发表的指南和文献中TBPET/CT的同行评审文章总结了共识,以及来自主要研究机构的专家的意见,总共在TBPET/CT扫描仪上进行了40,000例。
结果:该共识描述了常规和动态[18F]FDGTBPET/CT扫描的方案,重点是减少成像采集时间和FDG注射活动,这可以作为研究和临床肿瘤PET/CT研究的参考。
结论:本专家共识的重点是减少TBPET/CT扫描仪的采集时间和FDG注射活性,这可以提高患者的吞吐量或减少日常临床肿瘤成像中的辐射暴露。
结论:•[18F]肿瘤全身PET/CT采集时间缩短或FDG活性水平不同的FDG成像方案已从多中心研究中总结出来。•全身PET/CT提供更好的图像质量和改进的诊断见解。•改善了临床工作流程和患者管理。
BACKGROUND: [18F]FDG imaging on total-body PET/CT (TB PET/CT) scanners, with improved sensitivity, offers new potentials for cancer diagnosis, staging, and radiation treatment planning. This
consensus provides the protocols for clinical practices with a goal of paving the way for future studies with the total-body scanners in oncological [18F]FDG TB PET/CT imaging.
METHODS: The
consensus was summarized based on the published
guidelines and peer-reviewed articles of TB PET/CT in the literature, along with the opinions of the experts from major research institutions with a total of 40,000 cases performed on the TB PET/CT scanners.
RESULTS: This
consensus describes the protocols for routine and dynamic [18F]FDG TB PET/CT scanning focusing on the reduction of imaging acquisition time and FDG injected activity, which may serve as a reference for research and clinic oncological PET/CT studies.
CONCLUSIONS: This expert
consensus focuses on the reduction of acquisition time and FDG injected activity with a TB PET/CT scanner, which may improve the patient throughput or reduce the radiation exposure in daily clinical oncologic imaging.
CONCLUSIONS: • [18F]FDG-imaging protocols for oncological total-body PET/CT with reduced acquisition time or with different FDG activity levels have been summarized from multicenter studies. • Total-body PET/CT provides better image quality and improved diagnostic insights. • Clinical workflow and patient management have been improved.
