Clinical Trial Summary

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 gastrointestinal tumors, and compared with 18F-FDG PET/CT.


Clinical Trial Description

Subjects with gastrointestinal tumors underwent contemporaneous 18F-AlF-FAPI and 18F-FDG PET/CT either for an initial assessment or for recurrence detection. Tumor uptake was quantified by the maximum standard uptake value (SUVmax). The numbers of positive tumor 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. ;
