Correlations were robust in a heterogeneous clinical group but attenuated (although significant) in AD, suggesting that fluid and imaging biomarkers capture different aspects of tau pathology.Classification of evidence This study provides Class III evidence that, in a clinical sample of patients with a variety of suspected neurodegenerative diseases, both CSF p-tau and [18F]AV1451 distinguish AD from non-AD conditions.Aβ=β-amyloid; AD=Alzheimer disease; AUC=area under the curve; CI=confidence interval; GM=gray matter; LBNL=Lawrence Berkeley National Laboratory; MCI=mild cognitive impairment; MMSE=Mini-Mental State Examination; p-tau=phosphorylated tau; PHF-tau=paired helical filaments of tau; PiB=Pittsburgh compound B; ROC=receiver operating characteristic; SPM12=Statistical Parametric Mapping 12; SUVR=standard uptake value ratio; t-tau=total tau; UCSF=University of California San Francisco}, issn = {0028-3878}, URL = {//www.ez-admanager.com/content/90/4/e282}, eprint = {//www.ez-admanager.com/content/90/4/e282.full.pdf}, journal = {Neurology} }
