Table 5 Mean SUVmax and tumor-to-background ratio (TBR) with [68Ga]Ga-DOTATATE (SUVmax_Ga; TBRGa) and with [18F]AlF-OC (SUVmax_F; TBRF) at patient level for all concordant, quantifiable lesions (n = 153)

From: Prospective comparison of [18F]AlF-NOTA-octreotide PET/MRI to [68Ga]Ga-DOTATATE PET/CT in neuroendocrine tumor patients
