Flortaucipir off target binding
WebAug 12, 2024 · Several caveats should be considered when interpreting our results. First, 18 F-Flortaucipir shows considerable off-target binding in the hippocampus and basal ganglia, which may confound the assessment of tau pathology . Therefore, we excluded regions which are known to be affected by off-target binding.
