Labelling with Rhenium-188

There is considerable interest in $^{188}Re$ due to its favorable properties as a therapeutic radionuclide $^{188}Re$ and $^{99m}Tc$ act as a matched pair because of their similar chemical properties, and therefore methods of labeling with $^{99m}Tc$ can be applied to the labeling with $^{188}Re$. With appropriately chosen agents as carriers of $^{188}Re$, the labeling can be readily carried out using $^{188}ReO_4^-$ in the presence of a reducing agent. $^{188}Re$ radio-pharmaceuticals based on $^{99m}Tc$ complexes have been synthesized and are currently being studied for clinical use. Some of them are shown to be suitable for therapeutic use and promising for radiotherapy in nuclear medicine.
