For this study, 10 subjects with Alzheimer's underwent PET following the injection of three radiotracers: fluorine - 18 fluorodeoxyglucose (F - 18 FDG), which images regional metabolic activity; carbon - 11 Pittsburgh compound B (C - 11 PiB), which has an affinity for amyloid plaques; and F - 18 AV - 1451, an emerging imaging agent that binds to tau in the brain.

Now, a new imaging study of 10 people with mild AD suggests that tau deposits — not amyloid — are closely linked to symptoms such as memory loss and dementia.
