In the present study, we here report a case of 71-year-old woman, with bone destruction of L5 vertebral body showing lower of SUVmax for FAPI compared to FDG PET/CT imaging. To our knowledge, this present case is the first study to reveal that 68Ga-FAPI had lower tumour-to-background ratio in detecting bone metastasis from PTCMCa-FV.
