Influence of nuclides and chelators on imaging using affibody molecules : comparative evaluation of recombinant affibody molecules site-specifically labeled with ⁶⁸Ga and ¹¹¹In via maleimido derivatives of DOTA and NODAGA
Accurate detection of cancer-associated molecular abnormalities in tumors could make cancer treatment more personalized. Affibody molecules enable high contrast imaging of tumor-associated protein expression shortly after injection. The use of the generator-produced positron-emitting radionuclide (68)Ga should increase sensitivity of HER2 imaging. The chemical nature of radionuclides and chelators
