WebOct 14, 2024 · Purpose [18 F]flortaucipir binds to paired helical filament tau and accurately identifies tau in Alzheimer’s disease (AD).However, “off-target” binding interferes with the quantification of [18 F]flortaucipir in several brain regions.Recently, other tau PET tracers have been developed. Here, we compare [18 F]flortaucipir with the novel tau tracer [18 … WebJan 3, 2024 · Notably, off-target binding of 18 F-flortaucipir in the choroid plexus, brainstem, basal ganglia, and meninges has been reported . Although 18 F-flortaucipir PET imaging depicts tau deposition in the brain, it is crucial to note that a scan positive for tau deposition should be interpreted in association with amyloid PET imaging and clinical ... WebFeb 1, 2024 · Therefore, the variability in the signal in cohorts with low tau deposition related to off-target binding should be considered when examining early tau deposition using 18 F-flortaucipir. CONCLUSION Static scanning protocols provide accurate estimates of specific 18 F-flortaucipir binding in observational studies. highland park middle school nj
