Abstract

Objective: 18 F‐flortaucipir (formerly 18 F‐AV1451 or 18 F‐T807) binds to neurofibrillary tangles in Alzheimer disease, but tissue studies assessing binding to tau aggregates in progressive supranuclear palsy (PSP) have yielded mixed results. We compared in vivo 18 F‐flortaucipir uptake in patients meeting clinical research criteria for PSP (n = 33) to normal controls (n = 46) and patients meeting criteria for Parkinson disease (PD; n = 26). Methods: Participants underwent magnetic resonance imaging and positron emission tomography for amyloid‐β (11 C‐PiB or 18 F‐florbetapir) and tau (18 F‐flortaucipir). 18 F‐flortaucipir standardized uptake value ratios were calculated (t = 80–100 minutes, cerebellum gray matter reference). Voxelwise and region‐of‐interest group comparisons were performed in template space, with receiver operating characteristic curve analyses to assess single‐subject discrimination. Qualitative comparisons with postmortem tau are reported in 1 patient who died 9 months after 18 F‐flortaucipir. Results: Clinical PSP patients showed bilaterally elevated 18 F‐flortaucipir uptake in globus pallidus, putamen, subthalamic nucleus, midbrain, and dentate nucleus relative to controls and PD patients (voxelwise p < 0.05 family wise error corrected). Globus pallidus binding best distinguished PSP patients from controls and PD (area under the curve [AUC] = 0.872 vs controls, AUC = 0.893 vs PD). PSP clinical severity did not correlate with 18 F‐flortaucipir in any region. A patient with clinical PSP and pathological diagnosis of corticobasal degeneration had severe tau pathology in PSP‐related brain structures with good correspondence between in vivo 18 F‐flortaucipir and postmortem tau neuropathology. Interpretation: 18 F‐flortaucipir uptake was elevated in PSP versus controls and PD patients in a pattern consistent with the expected distribution of tau pathology. Ann Neurol 2017;82:622–634

  • Earlier PET investigations have detected alterations in PSP with ligands for tau and for microglial activation.

    “Previous positron emission tomography (PET) has indicated changes in PSP using ligands targeting tau8–16 and microglial activation17,18.”
  • Only a few previous studies have explored how [11C]PK11195 and [18F]AV-1451 binding relate to disease severity in PSP.

    “This finding adds relevant information to the literature as only a few previous studies have explored how [11C]PK11195 and [18F]AV-1451 binding relate to disease severity in PSP8,9,13,14,16,18.”
  • In PSP, higher [18F]AV-1451 binding is found in subcortical rather than cortical regions, consistent with the known distribution of PSP-Richardson's syndrome.

    “In PSP, higher [18F]AV-1451 binding has been found in sub-cortical rather than cortical regions (the reverse for AD), consistent with the well-established cortical versus sub-cortical distribution of PSP-Richardson’s syndrome8–10,13,14,16.”

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.
