description: | Purpose [ 11 C]PIB and [ 18 F]FDDNP are PET tracers for in vivo detection of the neuropathology underlying Alzheimer’s disease (AD). [ 18 F]FDG is a glucose analogue and its uptake reflects metabolic activity. The purpose of this study was to examine longitudinal changes in these tracers in patients with AD or mild cognitive impairment (MCI) and in healthy controls. Methods Longitudinal, paired, dynamic [ 11 C]PIB and [ 18 F]FDDNP (90 min each) and static [ 18 F]FDG (15 min) PET scans were obtained in 11 controls, 12 MCI patients and 8 AD patients. The mean interval between baseline and follow-up was 2.5 years (range 2.0–4.0 years). Parametric [ 11 C]PIB and [ 18 F]FDDNP images of binding potential (BP ND ) and [ 18 F]FDG standardized uptake value ratio (SUVr) images were generated. Results A significant increase in global cortical [ 11 C]PIB BP ND was found in MCI patients, but no changes were observed in AD patients or controls. Subsequent regional analysis revealed that this increase in [ 11 C]PIB BP ND in MCI patients was most prominent in the lateral temporal lobe ( p |
