To evaluate the potential usefulness of 18F-FIAT-2, 18F-C05-05, 18F-SPAL-T-06 positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in various α-Syn-related disease patients.
Subjects with various α-Syn-related disease patients underwent 18F-FIAT-2, 18F-C05-05, 18F-SPAL-T-06 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-FIAT-2, 18F-C05-05, 18F-SPAL-T-06 PET/CT were calculated.
