Yttrium-90 ((90)Y) radioembolization is a catheter-based therapy that delivers internal radiation to hepatic tumors in the form of microspheres. (90)Y can be delivered to the hepatic tumor as either a constituent of a glass microsphere, TheraSphere(®), or as a biocompatible resin-based microsphere, SIR-Spheres(®). Once embedded within the tumor microcirculation, these microspheres emit β-radiation at therapeutic levels. While the technical aspects of radioembolization are quite complex, the… CONTINUE READING
