From: Comparative analysis of two timepoints on [18F]FAPI-42 PET/CT in various cancers
A 49-year-old woman with multiple bone metastasis of differentiated thyroid cancer. a Comparison of maximum-intensity projection images between early and late [18F]FAPI-42 PET (lesions indicated by arrows). b PET/CT images on early and late [18F]FAPI-42 PET (arrows indicate metastatic lesions). Early [18F]FAPI-42 PET detected more metastatic bone lesions than late [18F]FAPI-42 (SUVmax of humerus lesion is 4.9 and 2.4, respectively; SUVmax of vertebrae is 7.6 and 6.4, respectively; SUVmax of femur is 4.8 and 4.1)
