Abstract

INTRODUCTION: Neuroimaging biomarkers are important for early diagnosis of Alzheimer's disease, and comparing multimodality neuroimaging to autopsy data is essential. METHODS: F-fluorodeoxyglucose PET (FDG-PET), and MRI. Correlations between neuroimaging biomarkers and neuropathologic schemes were assessed. RESULTS: PiB-PET showed strong correlations with Thal amyloid phase and Consortium to Establish a Registry for Alzheimer's Disease score and categorized 44% of Thal phase 1 participants as positive. FDG-PET and MRI correlated modestly with Braak tangle stage in Alzheimer's type pathology. A subset of participants with "none" or "sparse" neuritic plaque scores had elevated PiB-PET signal due to diffuse amyloid plaque. Participants with findings characterized as "suspected non-Alzheimer's pathophysiology" represented 15% of the group. DISCUSSION: PiB-PET is associated with Alzheimer's disease, neuritic plaques, and diffuse plaques. FDG-PET and MRI have modest correlation with neuropathologic schemes. Participants with findings characterized as suspected non-Alzheimer's pathophysiology most commonly had primary age-related tauopathy.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Antemortem AD neuropathologic diagnosis can be made with reasonable validity using CSF or PET biomarkers as surrogate markers for cerebral Aβ and tau deposition.

    “Antemortem AD neuropathologic diagnoses can now be made with reasonable validity using cerebrospinal fluid (CSF) or positron emission tomography (PET) imaging biomarkers as surrogate markers for cerebral Aβ and tau deposition”

    From Alzheimer Disease: An Update on Pathobiology and Treatment Strategies (2019) · cites this paper as Lowe et al., 2019

  • Antemortem AD diagnosis relies heavily on the presence of Aβ and tau, either measured in spinal fluid or imaged using positron emission tomography.

    “Antemortem diagnosis also relies heavily on the presence of Aβ and tau, either as measured in the spinal fluid or imaged using positron emission tomography (PET) [7–10].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
