Figure 4. — Time stability of the outcome parameters in different brain regions. V_T _(IDIF) and K_{1 (IDIF)} calculated using 1TCM (a and b) and V_T
(IDIF) based on Logan plot (c) normalized to the values obtained during 90-min acquisition. Correlations of the outcome parameters V_{T (IDIF)} and K_{1 (IDIF)} calculated using 1TCM (d and e) and V_{T (IDIF)} based on Logan plot (f) when shortening the acquisition time from 90 to 60 min. n = 10. 1TCM = one-tissue compartmental model, V_{T (IDIF)} = total volume of distribution using IDIF.
