Comparison of 68Ga-DOTATATE PET/CT and 18FDG PET/CT for detection of poorly and well-differentiated neuroendocrine tumours. 68Gallium radiolabelled somatostatin analogue PET/CT is more sensitive for identifying well-differentiated tumours in which the somatostatin receptor expression is preserved on neuroendocrine cells. 18FDG PET/CT is more sensitive for identifying poorly differentiated tumours in which the somatostatin receptor expression has been lost. Please note that the comparison images are from from different patients to illustrate differences in detail by modality based on the differentiation of the tumour. Images provided by Dr. David Chan (Department of Medicine, Sunnybrook Health Sciences Centre, University of Toronto, Toronto, Ont.). FDG = fluorodeoxyglucose, PET/CT = positron emission tomography–computed tomography.
