Flortaucipir (18F-AV-1451, also known as 18F-T807) is a highly selective positron emission tomography (PET) imaging agent targeting paired helical filament (PHF)-tau in the brain. This tracer is studying for clinical assessment in patients with various tauopathies, including Alzheimer's disease, as well as in healthy subjects.

In Vivo Use Guide

Flortaucipir PET images were acquired for 20 min, as four 5-min frames, beginning 80 min after injection of 370 MBq flortaucipir. On a separate day, subjects underwent a florbetapir PET scan for 10 min, as two 5-min frames, beginning 50 min after injection of 370 MBq florbetapir F18.
