Glucagon-like Peptide-1 Receptor PET/CT in GLP-1R Related Disease

February 7, 2025 updated by: Shaobo Yao, PhD, Tianjin Medical University
To evaluate the potential usefulness of 68Ga/18F-Exendin 4 positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in various GLP-1R-related disease patients.

Detailed Description

Subjects with various GLP1-R-related disease patients underwent 68Ga/18F-Exendin 4 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 68Ga/18F-Exendin 4 PET/CT were calculated.
