Hi Cafa, thanks for your detail description of the SIR-Spheres^®Y-90 procedure.

Please refer to the Sirtex document "SIR-Spheres Y-90 resin microspheres Bibliography: 31 May 2018", there are 1,017 occurrences of the word "radioembolization". https://www.radiologyinfo.org/en/info.cfm?pg=radioembol helps to confirm my understanding of embolization.

Radioembolization (Y90)

Radioembolization is a minimally invasive procedure that combines embolization and radiation therapy to treat liver cancer. Tiny glass or resin beads filled with the radioactive isotope yttrium Y-90 are placed inside the blood vessels that feed a tumor. This blocks the supply of blood to the cancer cells and delivers a high dose of radiation to the tumor while sparing normal tissue. It can help extend the lives of patients with inoperable tumors and improve their quality of life.
