- Table 1 shows the sensitivity and specificity comparison between FAPI PET and FDG PET imaging in each considered cancer type including the detection of primary tumour and metastatic lesions. This conclusion was derived from the published studies of FAPI vs. FDG comparison which were referred throughout the text. The darkest gray colour indicates “FAPI is superior to FDG”. The lighter gray colour indicates “FAPI surpasses FDG although there are non-significant or controversial findings”. The lighest gray colour indicates “FAPI is inferior to FDG including non-significant findings in some studies”. The striped box indicates “FAPI is comparable to FDG”. “NA” means that enough data is not available
