  1. Mean ± SD (CoV); data are obtained by NLR analysis based on BSIFs. CMRglu, cerebral metabolic rate of glucose consumption (in μmol/cm3 per minute (n = 9)); K 1, rate constant from blood to tissue (in min-1 (n = 9)); CBF, cerebral blood flow (in mL/cm3 per minute (n = 11)); V T, volume of distribution (unitless, obtained by CBF measurements (n = 11)); E, FDG extraction fraction (in % (n = 8)).
