Detailed Description
18F-SMBT-1, the novel 18F-labeled MAO-B PET tracer, was evaluated reactive astrogliosis in Alzheimer's disease successfully. In this prospective study, we assess the changes of reactive astrocytes in cerebral gray matter and white matter on Parkinson's disease by 18F-SMBT-1 PET/CT imaging among Chinese population.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
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
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.

Outcome Measures
Primary Outcome Measures
- Standard uptake value ratio (SUVR) [60 days]
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
- Clinical parameters [60 days]
Clinical parameters include sex, age, Hoehn-Yahr Stage, and Unified Parkinson's disease rating scale (UPDRS).
Secondary Outcome Measures
- Correlation coefficient 1 [60 days]
Correlation analysis of SUVR between 18F-SMBT-1, 18F-FP-CIT and 18F-FDG in the key cerebral regions.
- Correlation coefficient 2 [60 days]
Correlation analysis between SUVR of 18F-SMBT-1 PET/CT in the key cerebral regions and clinical parameters.
