Time–activity curves (TACs). TAC of blood sampling radioactivity in 5 healthy subjects (a) and TAC of PET image-derived blood radioactivity: average values from 5 healthy subjects (b). Both the TACs showed a peak within five min after the FBPA injection, gradually approaching a constant level at 20 min after the injection
