64Cu-Labeled tetraiodothyroacetic acid-conjugated liposomes for PET imaging of tumor angiogenesis

These results demonstrate that tetrac/64Cu-DOTA-liposomes have significantly enhanced tumor uptake compared to 64Cu-DOTA-liposomes due to tetrac conjugation. Further studies are warranted to reduce the liver and spleen uptake of tetrac/64Cu-DOTA-liposomes.
