All patients underwent clinical assessment, (18)F-AV-1451 PET, MRI, and quantification of β-amyloid pathology. A subset of participants also underwent (18)F-FDG-PET.In the 8 patients with CBS, 6 had imaging findings compatible with the corticobasal degeneration pathology and 2 with typical AD pathology. In the 6 patients with CBS without typical AD pathology, there were substantial retentions of (18)F-AV-1451 in the motor cortex, corticospinal tract, and basal ganglia contralateral to the most affected body side. These patients could be clearly distinguished from patients with AD dementia or PSP using (18)F-AV-1451. However, cortical atrophy was more widespread than the cortical retention of (18)F-AV1451 in these CBS cases, and cortical AV-1451 uptake did not correlate with cortical thickness or glucose hypometabolism. These results are in sharp contrast to AD dementia, where (18)F-AV-1451 retention was more widespread than cortical atrophy, and correlated well with cortical thickness and hypometabolism.Patients with CBS without typical AD pathology exhibited AV-1451 retention in the motor cortex, corticospinal tract, and basal ganglia contralateral to the affected body side, clearly different from controls and patients with AD dementia or PSP. However, cortical atrophy measured with MRI and decreased (18)F-fluorodeoxyglucose uptake were more widespread than (18)F-AV-1451 uptake and probably represent earlier, yet less specific, markers of CBS.This study provides Class III evidence that (18)F-AV-1451 PET distinguishes between CBS and AD or PSP.
