A suspension comprising radioactive microspheres. The radioactive microsphere comprises a resin microsphere and a radionuclide loaded on the resin microsphere, wherein the average particle size of the radioactive microsphere is 25 μm to 40 μm. By means of controlling the proportion of non-spherical microspheres in the radioactive microspheres to be within 5%, the distribution density of the microspheres at a tumor part is increased, the effect of killing tumors is improved, and the treatment safety is improved.
A suspension comprising radioactive microspheres, wherein the radioactive microspheres comprise resin microspheres and radionuclides loaded on the resin microspheres, have an average particle size of 25 μm to 40 μm, and have a non-spherical ratio of 5% or less.
A method for preparing a suspension comprising radioactive microspheres, wherein the method comprises:
