Research Abstract

To visualize the microglial cells in the brain using positron emission tomography (PET), the development and preclinical evaluation of purinergic receptor PET ligands have been demonstrated. P2Y12 receptor ligand [11C]clopidogrel and adenosine A2a ligand [11C]TMSX have been investigated, however both ligands fail to detect the microglial cells in the brain.
