Correlation of striatal BPND obtained from 60-min acquisition with BPND obtained from 90-min acquisition (a, b), and correlation of SUVr – 1 with BPND obtained from 60-min acquisition (c, d). (a, c) BPND was predicted by SRTM; (b, d) BPND was predicted by RLogan. .
Mid: midbrain, Cere: cerebellum, Occtx: occipital cortex; SRTM: simplified reference tissue model; RLogan: reference tissue Logan plot.
