Abstract

Background: [ 11 C]Pittsburgh compound B ([ 11 C]PIB) and [ 18 F]‐2‐fluoro‐2‐deoxy‐D‐glucose ([ 18 F]FDG) PET measure fibrillar amyloid‐β load and glucose metabolism, respectively. We evaluated the impact of these tracers on the diagnostic process in a memory clinic population. Methods: One hundred fifty‐four patients underwent paired dynamic [ 11 C]PIB and static [ 18 F]FDG PET scans shortly after completing a standard dementia screening. Two‐year clinical follow‐up data were available for 39 patients. Parametric PET images were assessed visually and results were reported to the neurologists responsible for the initial diagnosis. Outcome measures were (change in) clinical diagnosis and confidence in that diagnosis before and after disclosing PET results. Results: [ 11 C]PIB scans were positive in 40 of 66 (61%) patients with a clinical diagnosis of Alzheimer's disease (AD), 5 of 18 (28%) patients with frontotemporal dementia (FTD), 4 of 5 (80%) patients with Lewy body dementia, and 3 of 10 (30%) patients with other dementias. [ 18 F]FDG uptake patterns matched the clinical diagnosis in 38 of 66 (58%) of AD patients, and in 6 of 18 (33%) FTD patients. PET results led to a change in diagnosis in 35 (23%) patients. This only occurred when prior diagnostic certainty was <90%. Diagnostic confidence increased from 71 ± 17% before to 87 ± 16% after PET ( p < .001). Two‐year clinical follow‐up ( n = 39) showed that [ 11 C]PIB and [ 18 F]FDG predicted progression to AD for patients with mild cognitive impairment, and that the diagnosis of dementia established after PET remained unchanged in 96% of patients. Conclusions: In a memory clinic setting, combined [ 11 C]PIB and [ 18 F]FDG PET are of additional value on top of the standard diagnostic work‐up, especially when prior diagnostic confidence is low.

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?

  • A similar proportion of individuals clinically diagnosed as AD dementia have normal amyloid PET or CSF Aβ42 studies.

    “and a similar proportion has normal amyloid PET or CSF Aβ42 studies [53–62].”
  • Amyloid PET is part of biomarker screening in AD diagnostic criteria.

    “It is part of the biomarker screening in the AD diagnostic criteria and can help particularly in the diagnosis of young onset AD and differentiate from other dementias such as bvFTD [156, 157].”

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.
