abstract = {Corticobasal syndrome is associated with cerebral protein
aggregates composed of 4-repeat $(~50\%$ of cases) or mixed
3-repeat/4-repeat tau isoforms $(~25\%$ of cases) or
nontauopathies $(~25\%$ of cases).The aim of this
single-center study was to investigate the diagnostic value
of the tau PET-ligand [18 F]PI-2620 in patients with
corticobasal syndrome.Forty-five patients (71.5 ± 7.6
years) with corticobasal syndrome and 14 age-matched healthy
controls underwent [18 F]PI-2620-PET. Beta-amyloid status
was determined by cerebral β-amyloid PET and/or CSF
analysis. Subcortical and cortical [18 F]PI-2620 binding was
quantitatively and visually compared between
β-amyloid-positive and -negative patients and controls.
Regional [18 F]PI-2620 binding was correlated with clinical
and demographic data.Twenty-four percent (11 of 45) were
β-amyloid-positive. Significantly elevated [18 F]PI-2620
distribution volume ratios were observed in both
β-amyloid-positive and β-amyloid-negative patients versus
controls in the dorsolateral prefrontal cortex and basal
ganglia. Cortical [18 F]PI-2620 PET positivity was
distinctly higher in β-amyloid-positive compared with
β-amyloid-negative patients with pronounced involvement of
the dorsolateral prefrontal cortex. Semiquantitative
analysis of [18 F]PI-2620 PET revealed a sensitivity of
$91\%$ for β-amyloid-positive and of $65\%$ for
β-amyloid-negative cases, which is in excellent agreement
with prior clinicopathological data. Regardless of
β-amyloid status, hemispheric lateralization of [18
F]PI-2620 signal reflected contralateral predominance of
clinical disease severity.Our data indicate a value of [18
F]PI-2620 for evaluating corticobasal syndrome, providing
quantitatively and regionally distinct signals in
β-amyloid-positive as well as β-amyloid-negative
corticobasal syndrome. In corticobasal syndrome, [18
F]PI-2620 may potentially serve for a differential diagnosis
and for monitoring disease progression. © 2021 The Authors.
