Evaluating the Usefulness of 18F-AlF-FAPI PET/ CT in Orbital Neoplasms

January 19, 2025 updated by: Peking University Third Hospital

Evaluating the Potential Usefulness of 18F-AlF-FAPI PET/ CT in Patients with Orbital Neoplasms and Compared with 18F-FDG PET/ CT

To evaluate the potential usefulness of 18F-AlF-FAPI positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in orbital neoplasms, and compared with 18F-FDG PET/CT.

Detailed Description

Subjects with orbital neoplasms underwent contemporaneous 18F-AlF-FAPI and 18F-FDG PET/CT for initial assessment. Tumor uptake was quantified by the maximum standard uptake value (SUVmax). The numbers of metastatic lesions of 18F-FDG and 18F-AlF-FAPI PET/CT were recorded by visual interpretation. The sensitivity, specificity, and accuracy of 18F-AlF-FAPI, 18F-FDG PET/CT were calculated and compared to evaluate the diagnostic accuracy.
