Study Overview
Brief Summary
To evaluate the potential usefulness of 18F-92/AV45, 11C-PIB positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in various Tau-related disease patients.
Detailed Description
Subjects with various Tau-related disease patients underwent 18F-92/AV45, 11C-PIB 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-92/AV45, 11C-PIB PET/CT were calculated.
