CA1-specific tau signal detection

upin humans1

1 study
  1. CA1 and prosubiculum tau-pet roi improves CA1-specific tau signal detection in humans.

    “Seven other discordant cases were considered hippocampal‐sparing using the whole hippocampus scheme despite showing significant tau signal specifically in CA1. The CA1 and prosubiculum ROI was able to capture this signal”

Choroid plexus off-target binding false positives

1 study
  1. CA1 and prosubiculum tau-pet roi decreases choroid plexus off-target binding false positives in humans.

    “Visual inspection confirmed these as false positives driven by off‐target binding in the choroid plexus. This off‐target binding did not affect the CA1 and prosubiculum ROI”

Discordant staging cases

downin humans1

1 study
  1. CA1 and prosubiculum tau-pet roi decreases discordant staging cases in humans (-65% (15 [1.78%] vs 44 [5.22%])).

    “The CA1 and prosubiculum staging resulted in 15 (1.78%) discordant cases, 65% less than the whole hippocampus staging (44, 5.22%).”
