The imaging characteristics of [18F]PI-2620 using positron emission tomography (PET) in patients with progressive supranuclear palsy, Richardson's syndrome (PSP-RS) will be evaluated by a) determining the test-retest variability of the [18F]PI-2620 binding parameters in brain of patients with PSP-RS and non-demented controls (NDC).
The overall goal of this protocol is to evaluate the imaging characteristics of [18F]PI-2620 using positron emission tomography (PET) in patients with progressive supranuclear palsy, Richardson's syndrome (PSP-RS)
