Safety and Feasibility of Radioembolization Using Ho-166 in Patients With Unresectable Hepatocellular Carcinoma

This technic consists of the intra-arterial infusion of smaller beads that are loaded with a radioactive isotope (yttrium-90), and it relies on the beta radiation emitted by the isotope to induce tumor necrosis, with a minor contribution from microembolization and without risk of ischemia of the remaining liver.
