  • * Rate constants for white matter were used to compute lCMRglc of cerebellar white matter and internal capsule; for all other structures, rate constants for gray matter were used. Lumped constants for FDG of 0.71 ± 0.12 and 0.68 ± 0.03, obtained in paired and unpaired animals, were not statistically significantly different.
