MULTIFUNCTIONAL MICROSPHERE PREPARATION FOR CHEMOEMBOLIZATION THERAPY AND IMAGING OF TUMORS, AND PREPARATION METHOD THEREFOR

摘要

A microsphere preparation for chemoembolization therapy and nuclear medicine imaging of tumors, and a preparation method therefor. The microsphere is formed by means of using a polyvinyl alcohol derivative as a framework material and polymerizing, crosslinking and curing same with an N-acryloyl amino acid monomer. The microsphere can label radionuclide iodine and can also absorb and load chemotherapeutic drugs.
