A fundamental task within the framework of a project searching for new radiopharmaceuticals for systemic therapy was the evaluation of the capabilities of the Portuguese Research Reactor (RPI) for the production of several important radionuclides. The feasibility of producing 64Cu, 77As, 153Sm, 165Dy, 166Ho, 170Tm, 177Lu, 186Re, 199Au and 111Ag in useful quantities was evaluated for the present...

Liver radioembolization is a treatment option for unresectable liver cancers, performed by infusion of 90Y or 166Ho loaded spheres in the hepatic artery. As tumoral cells are mainly perfused via artery unlike lobules, twofold tumor to normal dose ratio commonly obtained. To improve cell killing while preserving co-infusion arterial vasoconstrictor has been proposed but with limited success: buf...

introduction:holmium-166 radionuclide is one of the most effective radionuclides used for targeted therapy with theranostic properties. one method to produce this radioisotope is via the decay of its parent (indirect method). in this study applicability of extraction chromatography (exc) for separation of no carrier added 166ho from neutron-irradiated natural dysprosium target followed by quali...
