An observational study in Neuroinflammation, Stroke and Neurodegenerative Diseases, 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-DPA714/FDPA positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in various TSPO-related disease patients.
Subjects with various Tau-related disease patients underwent 18F-DPA714/FDPA 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-DPA714/FDPA PET/CT were calculated.
8,255 studies on the registry are indexed under Stroke; 2,056 are open to participants now.
This study's planned enrollment of 200 is above the median of 152 across 1,968 observational studies indexed under Stroke.

Compared within Stroke, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Neuroinflammatory Diseases. The counts are of registry records indexed under each term, refreshed daily. How we classify →
(i) adult patients (aged 18 years or order); (ii) patients with suspected or new diagnosed or previously treated malignant tumors (supporting evidence may include MRI, CT, tumor markers and pathology report); (iii) patients who had scheduled TSPO PET/CT scan; (iv) patients who were able to provide informed consent (signed by participant, parent or legal representative) and assent according to the guidelines of the Clinical Research Ethics Committee.

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.
