Brief summary

To evaluate the potential usefulness of 11C/18F-HED 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 sympathetic nerves-related disease patients underwent 11C/18F-HED 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 11C/18F-HED PET/CT were calculated.

Interventions

DIAGNOSTIC_TEST11C/18F-HED

Each subject receive a single intravenous injection of 11C/18F-HED and undergo PET/CT or MRI imaging within the specificed time.
