An observational study in Tauopathies, Neurodegenerative Diseases and Neurodegeneration, sponsored by Tianjin Medical University. Recruiting at 3 sites in China. Open to participants aged 18 Years to 80 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-08.
Sponsored by Tianjin Medical University · Observational
To evaluate the potential usefulness of 18F-S16/T807 positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in various Tau-related disease patients.
Subjects with various Tau-related disease patients underwent 18F-S16/T807 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-S16/T807 PET/CT were calculated.
75 studies on the registry are indexed under Tauopathies; 18 are open to participants now.
This study's planned enrollment of 500 is above the median of 50 across 18 observational studies indexed under Tauopathies.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
