About this study
To evaluate the potential usefulness of 18F-FPyCO/SMBT-1 positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in various MAO-B-related disease patients.
Read the detailed description
Subjects with various Tau-related disease patients underwent18F-FPyCO/SMBT-1 PET/CT either for an initial assessment or for recurrence detection. Lesions uptake was quantified by the maximum standard uptake value (SUVmax). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of 18F-FPyCO/SMBT-1 PET/CT were calculated.
- Being tested

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Diagnostic Test: 18F-FPyCO/SMBT-1Diagnostic test
Each subject receive a single intravenous injection of 18F-FPyCO/SMBT-1, and undergo PET/ CT or MRI imaging within the specificed time.

Questions about this trial
What is this clinical trial studying?
An observational study of Parkinson Disease and Parkinson Disease Dementia, run by Tianjin Medical University at 3 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 8 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ying Wang, MD (+8618702292537, macrossplusvoices@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Standardized uptake value (SUV) (time frame: 30 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Sep 2026.
