Abstract

Formation of senile plaques composed of amyloid beta peptide, a pathological hallmark of Alzheimer disease, in human brains precedes disease onset by many years. Noninvasive detection of such plaques could be critical in presymptomatic diagnosis and could contribute to early preventive treatment strategies. Using amyloid precursor protein (APP) transgenic mice as a model of amyloid beta amyloidosis, we demonstrate here that an intravenously administered (19)F-containing amyloidophilic compound labels brain plaques and allows them to be visualized in living mice by magnetic resonance imaging (MRI) using (19)F and (1)H. Our findings provide a new direction for specific noninvasive amyloid imaging without the danger of exposure to radiation. This approach could be used in longitudinal studies in mouse models of Alzheimer disease to search for biomarkers associated with amyloid beta pathology as well as to track disease course after treatment with candidate medications.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • The plaques showed hypointensity in MRI images and increased with age in both cortex and hippocampus regions, consistent with previous findings.

    “The plaques showed hypointensity in MRI images and increased with age in both cortex and hippocampus regions, which is consistent with several previous findings (Higuchi et al., 2005; Meadowcroft et al., 2009).”

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.
