What the grant funds

This Notice of Funding Opportunity (NOFO) invites research grant applications that propose the development and evaluation of novel radioligands for positron emission tomography (PET) or single photon emission computed tomography (SPECT) imaging in human brain and the incorporation of, pilot or clinical feasibility evaluation from previously collected data in pre-clinical studies. These studies are expected to provide the requisite data needed to advance promising PET ligands for use in clinical research.
