↵* Logan (22) analysis using metabolite-corrected arterial input (method 1), uncorrected arterial input (method 2), or cerebellar time–activity curve input (method 3); simplified reference tissue model (method 4) (28); and standard compartmental modeling (method 5).
↵† Significantly different (P < 0.05) compared with method 1.
FC = frontal cortex; CC = cingulate cortex; INS = insular cortex; LTC = lateral temporal cortex; MTC = medial temporal cortex.
Data are listed as mean ± SD (n = 6).
