Abstract
Radioembolization aims to selectively target radiation to all liver tumors while limiting the dose to normal liver parenchyma. The deposition of yttrium-90 (90Y) microspheres delivered through the hepatic artery are preferentially implanted within liver tumors in a 3:1 to 20:1 ratio compared with a normal liver. The principles and mode of action of radioembolization are fundamentally different from the conventional embolization of liver tumors through transarterial embolization or chemoembolization.............The expanding literature on radioembolization shows that this is an effective treatment for the management of both primary and metastatic tumors.
