68Ga-DOTA-FAPI-04 PET/CT in Neuroendocrine Carcinoma of the Liver With Elevated AFP Level: Comparison With 18F-FDG PET/CT

A 68-year-old woman with a mass lesion in right hepatic lobe had an elevated α-fetoprotein level (>54,000 ng/mL). The lesion showed higher 68Ga-DOTA-FAPI-04 uptake than 18F-FDG uptake in consecutive PET/CT images. The histopathological examination revealed neuroendocrine carcinoma with Ki-67 proliferation index of 80%.
