  • The following kinetic parameters were assessed: VB, k1–k4, and influx for each individual acquisition interval. All correlation coefficients for VB and k1 are significant on P < 0.01 level. Correlation coefficients for influx are significant for 2–60 min. Although influx was correlated mainly with late acquisition times, VB and k1 were correlated with early acquisition times.
