Abstract

Amyloid imaging is a valuable tool for research and diagnosis in dementing disorders. As positron emission tomography (PET) scanners have limited spatial resolution, measured signals are distorted by partial volume effects. Various techniques have been proposed for correcting partial volume effects, but there is no consensus as to whether these techniques are necessary in amyloid imaging, and, if so, how they should be implemented. We evaluated a two-component partial volume correction technique and a regional spread function technique using both simulated and human Pittsburgh compound B (PiB) PET imaging data. Both correction techniques compensated for partial volume effects and yielded improved detection of subtle changes in PiB retention. However, the regional spread function technique was more accurate in application to simulated data. Because PiB retention estimates depend on the correction technique, standardization is necessary to compare results across groups. Partial volume correction has sometimes been avoided because it increases the sensitivity to inaccuracy in image registration and segmentation. However, our results indicate that appropriate PVC may enhance our ability to detect changes in amyloid deposition.

  • Quality control reviewed post-processing PUP output was included for 1356 PET sessions.

    “Quality control reviewed post-processing PUP output 42,43 , which includes uptake measure for FreeSurfer-based regions, was included for 1356 PET sessions.”

    From OASIS-3: Longitudinal Neuroimaging, Clinical, and Cognitive Dataset for Normal Aging and Alzheimer Disease (2019) · cites this paper as [42]

    The Image Analysis section (page unavailable) describes quality assurance of FreeSurfer segmentation and PET uptake measures for FreeSurfer-defined regions, supporting the description of the output. It does not identify that output as PUP; the 1356-session count describes the citing authors’ dataset, not a result attributed to this source. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • Su et al. has demonstrated that the RSF technique was able to improve PET quantification and achieve better sensitivity to longitudinal changes in amyloid burden.

    “Su et al. 42,49 has demonstrated that the RSF technique was able to improve PET quantification and achieve better sensitivity to longitudinal changes in amyloid burden.”
  • PET imaging analyses were performed using the PET unified pipeline (PUP).

    “PET imaging analyses were performed using the PET unified pipeline 42,43 (PUP, https://github.com/ysu001/PUP) via XNAT on Dell PowerEdge 1950 servers with Intel Xeon processors running CentOS 5.5 Linux.”

    From OASIS-3: Longitudinal Neuroimaging, Clinical, and Cognitive Dataset for Normal Aging and Alzheimer Disease (2019) · cites this paper as [42]

    Section 2.3 (Image Analysis; page unavailable) describes PET processing methods, including FreeSurfer segmentation and in-house motion-correction software, but does not identify them as the PET unified pipeline. Searches for “PET unified pipeline,” “PUP,” and “pipeline” found no passage establishing that identification. The citation is attached to PUP, not the server details later in the sentence. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • Both types of PET data were partial volume corrected using a regional spread function technique.

    “Both types of PET data were partial volume corrected using a regional spread function technique27,28.”

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.
