Flortaucipir F-18 is a small lipophilic tracer containing [18F]fluoride capable of crossing the blood-brain barrier and binding to aggregated tau protein; used in PET imaging for the diagnosis of Alzheimer's disease.

Alzheimer's disease is a progressive neurodegenerative disease characterized by the build-up of hyperphosphorylated tau protein aggregates. Hyperphosphorylated tau forms dimers termed paired helical filaments (PHFs), which aggregate further to form neurofibrillary tangles (NFTs) associated with neurodegeneration and severity of Alzheimer's symptoms. Flortaucipir F-18 is a small molecule that contains radioactive F, which decays by positron emission to O with a half-life of 109.8 minutes. As a small relatively lipophilic molecule, flortaucipir F-18, following intravenous injection, quickly passes through systemic circulation, crosses the blood-brain barrier, and binds to NFTs. Once bound, the ensuing radioactive decay emits pairs of 511 keV gamma photons useful in diagnostic imaging. The pattern and intensity of emission during imaging is used in the diagnosis of Alzheimer's disease.
Flortaucipir F-18 is a radioactive agent indicated for positron emission tomography (PET) imaging of aggregated tau neurofibrillary tangles (NFTs) in adult patients under evaluation for Alzheimer's disease. Flortaucipir F-18 is not indicated for use in patients under evaluation for chronic traumatic encephalopathy.
