Superiority of 68Ga-DOTA-FAPI-04 PET/CT to 18F-FDG PET/CT in the evaluation of different cancers with bone metastases

⁶⁸Ga-DOTA-FAPI-04 as a novel imaging agent, can detect more bone metastases and has a higher tracer uptake level than ¹⁸F-FDG. Especially for lung and gastric cancer, ⁶⁸Ga-DOTA-FAPI-04 PET/CT may be a more reliable means to detect bone metastases.
