Post-radioembolization yttrium-90 PET/CT - SpringerOpen
2013年7月25日 · Encouraged by favorable early experiences, we implemented post-radioembolization 90 Y PET/CT as an adjunct to 90 Y bremsstrahlung SPECT/CT in diagnostic reporting. This is a retrospective review of all paired 90 Y PET/CT and 90 Y bremsstrahlung SPECT/CT scans over a 1-year period.
浅谈钇-90 PET显像的图像质量和扫描速度的问题 - 中国核技术网
2022年7月30日 · 钇-90(y-90)微球放射栓塞治疗技术是一种靶向肿瘤放射治疗，被广泛应用于肝脏恶性肿瘤的选择性体内放射治疗(sirt)中，它通过靶向的大剂量高能量β辐射杀死癌细胞，同时可以很好地保护健康肝脏组织。
Imaging of Y90 distribution with PET/CT and bremsstrahlung …
Objectives The absence of γ emission limits accurate scintigraphic dosimetry after radioembolization with Y90 microspheres (RE).SPECT/CT is currently recommended to evaluate the radioactive distribution and to rule out any extrahepatic shunting using bremsstrahlung (BS).Y90-PET/CT is recently being studied as an alternative modality.The aim of t...
Yttrium-90 internal pair production imaging using first generation PET …
Yttrium-90 (90Y) internal pair production can be imaged by positron emission tomography (PET)/CT and is superior to bremsstrahlung single-photon emission CT/CT for evaluating hepatic 90Y microsphere biodistribution. We illustrate a case of 90Y ...
Y90-PET-CT扫描 在 癌症-临床试验注册中心-ICH GCP
2023年10月31日 · y90-pet-ct 扫描将主要用于确认放射性示踪剂输送到目标病灶。 与 y90-轫致辐射-spect 扫描相比，y90-pet-ct 扫描被认为可以提供更高质量的图像；因此，使用 y90-pet-ct 图像时有望获得有关治疗成功/失败的更准确信息。 次要成果 - 使用从主要目标获得的优化 90y-pet-ct ...
Improving Yittrium-90 PET scan image quality through optimized ...
2022年11月9日 · The study aimed to improve the quality of the Y90 PET imaging by optimizing the reconstruction algorithm.
