Prognostic significance of 68 Ga-FAPI PET/CT in patients with bone metastases in various cancers

This study aimed to compare 18FDGPET/CT in patients who develop bone metastases due to various cancers and to investigate the prognostic significance of the 68FAPI-PET/CT SUVmax value for survival. Patients with bone metastases who underwent both 68 Ga-FAPI PET/CT and 18FDGPET/CT within a 1 week period were included in this retrospective study. The effect of the SUVmax value of bone lesions on overall survival was analyzed. A total of 75 eligible patients with 139 bone lesions were included in this study. The median age of the patients was 55 (30–83) and 48(64
