Outcome Measures

Primary Outcomes (2)

  • Standard uptake value ratio (SUVR)

    Standard uptake value ratio of 18F-SMBT-1, 18F-FP-CIT and 18F-FDG in the key cerebral regions using the cerebellar cortex or subcortical white matter as a reference region

    60 days

  • Clinical parameters

    Clinical parameters include sex, age, Hoehn-Yahr Stage, and Unified Parkinson's disease rating scale (UPDRS).

    60 days

Secondary Outcomes (2)

  • Correlation coefficient 1

    60 days

  • Correlation coefficient 2

Study Arms (2)

Parkinsonism patients

This group/cohort comprises clinically diagnosed as Parkinsonism, including Parkinson's disease and atypical Parkinsonism syndromes, and each participant is injected 18F-SMBT-1 (185-370Mbq) and underwent PET/CT scanning within 50-70 min after injection.

Drug: 18F-SMBT-1

Health control

Each participant is injected 18F-SMBT-1 (185-370Mbq) and underwent PET/CT scanning within 50-70 min after injection.

Drug: 18F-SMBT-1

Interventions

Each participant receives intravenous injection of 18F-SMBT-1, and undergo PET/CT imaging within the special time. 18F-FP-CIT and 18F-FDG PET/CT are used to assess the change of cerebral dopamine transporters and glucose metabolism for auxiliary diagnosis.

Also known as: 18F-FP-CIT, 18F-FDG
Health controlParkinsonism patients
