MIP image of an [18F]FDG PET/CT scan (A) and a [68Ga]Ga-DOTATATE PET/CT scan (D) performed during staging of a typical bronchial carcinoid tumour (TC) of a 62-year-old patient with a clear discrepancy between an intense [68Ga]Ga-DOTATATE uptake (E) and no increased [18F]FDG uptake (B) in the primary tumour (red arrow) as well as in a subcarinal lymph node metastasis (blue arrow). The axial fusion images with CT in bone window of the [18F]FDG PET/CT (C) and the [68Ga]Ga-DOTATATE PET/CT (F) also show this discrepancy with regard to the bone metastases. The bone metastasis in the left hemisacrum (yellow circle) has a SUVmax on [68Ga]Ga-DOTATATE PET/CT of 39.6. A chest CT 53 days before the [68Ga]Ga-DOTATATE PET/CT did not show any bone metastasis
