About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • (i) adult patients (aged 18 years or order); (ii) patients with suspected or new diagnosed or previously treated PD (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.

Exclusion criteria

  • patients with non-malignant lesions; (ii) patients with pregnancy; (iii) the inability or unwillingness of the research participant, parent or legal representative to provide written informed consent.

Treatment and study plan

Diagnostic Test: 18F-FPyCO/SMBT-1

Diagnostic Test

Each subject receive a single intravenous injection of 18F-FPyCO/SMBT-1, and undergo PET/ CT or MRI imaging within the specificed time.

    Time frame: 30 days

    Standardized uptake value (SUV) of 18F-FPyCO/SMBT-1 for each target lesion of subject or suspected PD.

Secondary outcomes

  1. Diagnostic efficacy

    Time frame: 30 days

    The sensitivity, specificity and accuracy of MAO-B PET/CT were calculated
