Provided are radiopaque compositions comprising one or more of yttrium (Y), strontium (Sr), gallium (Ga), and silicon, or oxides and salts thereof. The composition can comprise a combination of Y2O3, SrCO3, Ga2O3, and SiO2, and optionally MnO2, and TiO2. Other compositions comprise SrCO3, Ga2O3, TiO2, MnO2, and SiO2. The composition can be a particulate material. The compositions are useful for radioembolization to treat tumors. |
