Microspheres, Embolization, Brachytherapy
Definition : Embolization microspheres designed to give large local radiation (e.g., beta rays) to tumors with little radiation to the neighboring healthy tissues. These devices typically consist of glass or ceramic microspheres that include a radiopharmaceutical isotope (e.g., Yttrium-90) either bound to their surface or forming part of the microsphere structure. Radioactive embolization microspheres are mostly used for local radiotherapy (i.e., brachytherapy) of cancer tumors with simultaneous embolization of the vasculature (e.g., the hepatic artery for liver cancer) nourishing the tumors.
