Table 10.
Mean between-subject coefficients of variation (BSCV; %) for subjects' VT/BPND/mSUV parameters obtained with the different methods. ACG = anterior cingulate gyrus, IFG = inferior frontal gyrus, caudate = caudate nucleus, pallidum = globus pallidus, accumbens = nucleus accumbens. ROI = region-of-interest, SD = standard deviation, NA = not applicable.
