Superiority of 18F-FDG PET/CT to 68GA-FAPI PET/CT in Adrenocortical Tumor Imaging

F-18-FDG PET/CT was performed to evaluate the response to treatment in a 62-year-old female patient who was operated for adrenocortical carcinoma. High FDG uptake was observed in recurrent lesion in the left adrenal gland site and metastatic lesions. In the Ga-68-FAPI-04 PET/CT study, low FAPI uptake was observed in both recurrences and metastases. In this case, we demonstrated the superiority of F-18-FDG PET/CT over Ga-68-FAPI-04 PET/CT in the evaluation of adrenocortical carcinoma.

Automated summary

This study compared the efficacy of F-18-FDG PET/CT and Ga-68-FAPI-04 PET/CT in evaluating the response to treatment in a patient with adrenocortical carcinoma. It was found that F-18-FDG PET/CT showed higher uptake in recurrent and metastatic lesions than Ga-68-FAPI-04 PET/CT, indicating its superiority in this case.
