Units are shown in SUVR referenced to cerebellar cortices or to pons for FDG and SUVR referenced to pons for PiB
FDG Cb relative FDG uptake normalised to cerebellum, FDG Pon relative FDG uptake normalised to pons, ParTem parietotemporal, Fro frontal, PosCin/PC posterior cingulated and precuneus, Occ occipital, Stri striatum
* Significantly lower in DLB group compared with that in AD group (p < 0.05)
