Time–stability analysis. VT results are normalized to 2-tissue-compartment model/VT values measured at 120 min (n = 12) (A) and 210 min (n = 6) (B). ● = cerebellum and ○ = average of other brain regions. Although good stability was reached by 120 min in low-uptake regions of brain, cerebellum still showed upward trend at 120 min and eventually almost stabilized by 170 min. Higher SD bars after 160 min denote presence of subjects with aberrant VT values.
