From: Differential response to donepezil in MRI subtypes of mild cognitive impairment
Baseline MRI patterns characterized on continuous scales of subtyping dimensions. A Scatterplot of the hippocampus-to-cortex ratio (typicality subtyping dimension) by BV/CSF index (severity subtyping dimension). B Classification of MCI individuals according to the degree of global brain atrophy after applying clinical cut-offs on BV/CSF index (severity subtyping dimension). Note: BV = brain volume; CSF = cerebrospinal fluid
