  1. Values are SUVRs, using the cerebellar cortex as the reference region and are expressed as mean ± SD. Data were obtained at 30, 60, and 90 min post-tracer injection (n = 6). Superscripts * within rows indicate that the mean SUVR differs at 90 min as compared with that at 0 min by P < 0.05; a, b, c, d within columns indicate the mean SUVRs differ from that at the occipital cortex, temporal cortex, parietal cortex, and frontal cortex by P < 0.05; †Values for the composite comprise the average SUVRs for the frontal, parietal, temporal, occipital, anterior cingulate, and posterior cingulate cortices; SUVR Standardized uptake value ratio
