Application of 18F-CP6A PET Imaging in Synucleinopathies

For pharmacokinetics, healthy volunteers underwent PET imaging targeting α-synuclein. Blood samples were collected at before and 2 ± 1, 5 ± 2, 10 ± 2, 30 ± 5, 60 ± 5, 90 ± 5, and 120 ± 10 min after imaging agent injection, and urine specimens were collected at before and 0-1.5, and 1.5-3 h after injection to measure radioactivity in blood and urine. PET/MR and PET/CT scans were performed at 0 ± 10, 30 ± 10, 60 ± 10, and 100 ± 10 min after injection to understand distribution for healthy volunteers and synucleinopathy patients. A separate 10-minute PET scan of the brain is required of each acquisition. Blood tests, liver and kidney function, and other biochemical markers must be performed one week prior to and after imaging.
