Table 2.

Subjects' volume of distribution (V_T) obtained with two-compartment model (2kbv) method. ACG = anterior cingulate gyrus, IFG = inferior frontal gyrus, caudate = caudate nucleus, pallidum = globus pallidus, accumbens = nucleus accumbens. BS = between-subjects, CV = coefficient of variation, diff = difference, ICC = intraclass correlation coefficient, Min = minimum, Max = maximum, ROI = region-of-interest, SD = standard deviation.
