Histological Comparison of Kidney Tissue Following Radioembolization with Yttrium-90 Resin Microspheres and Embolization with Bland Microspheres

Background Intra-arterial brachytherapy with yttrium-90 (90Y) resin microspheres (radioembolization) is a procedure to selectively deliver high-dose radiation to tumors. The purpose of this research was to compare the radioembolic effect of 90Y-radioembolization versus the embolic effect of bland microspheres in the porcine kidney model.
