Safety of a Scout Dose Preceding Hepatic Radioembolization with 166Ho Microspheres.
UNLABELLED Before (166)Ho radioembolization, a small batch of the same type of microspheres is administered as a scout dose instead of the conventional (99m)Tc-macroaggregated albumin ((99m)Tc-MAA). The (166)Ho scout dose provides a more accurate and precise lung shunt assessment. However, in contrast to (99m)Tc-MAA, an unintended extrahepatic deposition of this β-emitting scout dose could infl...
متن کاملRadioembolization with selective internal radiation microspheres for neuroendocrine liver metastases.
BACKGROUND There are limited effective treatment options available and a poor 5-year survival for patients with inoperable neuroendocrine liver metastases (NETLMs). In this study, the authors prospectively assessed the safety and efficacy of treatment with yttrium 90 ((90)Y) radioactive microspheres for patients with unresectable NETLMs. METHODS Radioactive (90)Y resin microspheres (selective...
متن کاملHuman organ absorbed dose estimation of 166Ho-BPAMD complex based on biodistribution data of male Syrian rats
Introduction: Recently, 166Ho-BPAMD was introduced as a suitable agent for bone marrow ablation. The aim of this study was to estimate the absorbed dose of this novel agent in the human organs which is necessary before the clinical application. Methods: 166Ho was produced by direct irradiation of 165Ho in the research reactor. 250 µg...
متن کاملDetermination of Radiation Absorbed Dose to Primary Liver Tumors and Normal Liver Tissue Using Post-Radioembolization 90Y PET
BACKGROUND Radioembolization with Yttrium-90 ((90) Y) microspheres is becoming a more widely used transcatheter treatment for unresectable hepatocellular carcinoma (HCC). Using post-treatment (90) Y positron emission tomography/computerized tomography (PET/CT) scans, the distribution of microspheres within the liver can be determined and quantitatively assessed. We studied the radiation dose of...
