18F-FDG PET scans of two cognitively normal (NL) individuals with postmortem-confirmed AD parents. The 18F-FDG PET of the son of an AD father (left) shows no CMRglc abnormalities, while the 18F-FDG PET of the daughter of an AD mother (right) shows areas of reduced CMRglc (indicated by arrows) [7]. CMRglc measures are represented on a colour-coded scale, ranging from 0 to 60 μmol glucose/100 g/min (right side of figure).
