Clinical Trial Summary

To explore the diagnostic value of 18F-0502B brain imaging for α-Syn protein-related diseases in patients with PD. To evaluate the imaging range of α-Syn protein density in patients with α-Syn protein-related diseases and to assess the level of abnormal α-Syn protein deposition by PET imaging with this PET tracer, and its safety in human studies.
