A novel method for harmonization of PET image spatial resolution without phantoms

Félix Carbonell, Alex P. Zijdenbos, Evan Hempel, Mihály Hajós, Barry J. Bedell, Alzheimer’s Disease Neuroimaging Initiative

This paper introduces a method to estimate PET image spatial resolution without phantoms, validated on clinical and ADNI datasets, showing consistent results across tracers and scanners.

Tau-related reduction of glucose metabolism in mild cognitive impairment occurs independently of APOE ε4 genotype and is gradually modulated by β amyloid

Félix Carbonell, Carolann McNicoll, Alex P. Zijdenbos, Barry J. Bedell, Alzheimer’s Disease Neuroimaging Initiative

The paper investigates the relationship between tau PET, glucose metabolism, and beta-amyloid in MCI, finding that tau scores are strongly correlated with reduced glucose metabolism independently of APOE ε4 and modulated by beta-amyloid.

Spatial association between distributed β-amyloid and tau varies with cognition

Félix Carbonell, Carolann McNicoll, Alex P. Zijdenbos, Barry J. Bedell, Alzheimer’s Disease Neuroimaging Initiative

The paper introduces CDCA to analyze spatial associations between β-amyloid and tau in AD, finding cognition-dependent patterns not captured by traditional metrics.
