Ex Vivo Evaluation of Residual Activity and Infusion Dynamics in a Commercially Available Yttrium-90 Resin Microsphere Administration System

Purpose To evaluate the infusion dynamics and residual yttrium-90 activity during and after resin microsphere radioembolization with different injection techniques and initial activities. To assess the distribution of residual activity in the administration systems to allow optimization of the procedure and the equipment. Materials and Methods In a setup similar to that in standard clinical practice, radioembolization procedures were performed...
