<unk> (18F) (trade name AMYViD; also known as<unk> fluorine-18 or 18F-AV-45) is a PET scanning radiopharmaceutical compound containing the radionuclide fluorine-18, recently FDA approved as a diagnostic tool for Alzheimer's disease.<unk>  like Pittsburgh compound B (PiB), binds to beta-amyloid, but due to its use of fluorine-18 has a half-life of 110 minutes, in contrast to PiB's radioactive half life of 20 minutes. Wong et al. found that the longer life allowed the tracer to accumulate significantly more in the brains of people with AD, particularly in the regions known to be associated with beta-amyloid deposits.
One review predicted that amyloid imaging is likely to be used in conjunction with other markers rather than as an alternative.
