Y-90 radioembolization is a procedure that delivers radiation therapy directly to the tumors in the liver.
With the help of imaging guidance, an interventional radiologist makes a small incision and guides a tiny tube (called a catheter) into the artery that supplies blood to the liver. Micro beads containing the radioactive substance known as Y-90 are injected. The beads can travel into the small blood vessels that feed the liver tumors. Once inside, they can destroy the tumor from within. This procedure minimizes any damage to nearby healthy tissue.
