Florbetapir (18 F), sold under the brand name Amyvid, is a PET scanning radiopharmaceutical compound containing the radionuclide fluorine-18 that was approved for use in the United States in 2012, [4] as a diagnostic tool for Alzheimer's disease.
Chemical structure of florbetapir (18 F), with the fluorine-18 atom on top. Dr. Skovronsky established Avid Radiopharmaceuticals in July 2005 with the goal of finding a dye that could be injected into the body, would cross the blood–brain barrier and attach itself to amyloid protein deposits in the brain.

Flortaucipir (18 F) is a radioactive diagnostic agent for adults with cognitive impairment who are being evaluated for Alzheimer's disease. [1]It is indicated for positron emission tomography (PET) imaging of the brain to estimate the density and distribution of aggregated tau neurofibrillary tangles (NFTs), a primary marker of Alzheimer's disease.
Florbetaben, sold under the brand name Neuraceq, is a diagnostic radiotracer developed for routine clinical application to visualize β-amyloid plaques in the brain. It is a fluorine-18 (18 F)-labeled stilbene derivative.
The advantage of 18F-FDG PET for these uses is its much wider availability. Some radioactive tracers used for Alzheimer's are florbetapir 18F, flutemetamol F18, PiB and florbetaben 18F, which are all used to detect amyloid-beta plaques (a potential biomarker for Alzheimer's) in the brain.
A fully automated radiosynthesis interface of PET-radiotracers. PET is a functional imaging technique that produces a three-dimensional image of functional processes in the body.
Of the 176 patients imaged in this trial had a median age was 82, with 57 of patients being female. The initial flutemetamol PET scan resulted in 43 positive and 25 negative results for cerebral cortisol amyloid status. 69 of the initial patients died within 13 months of the flutemetamol PET scan.
