Over the last 2 decades, gallium\u201068 labelled somatostatin analogues have revolutionised SSTR imaging through the advent of SSTR positron emission tomography (PET), leading to better staging and theranostic imaging. Recent advances in the development of PET SSTR tracers continue to change the field, with novel tracers labelled with different radionuclides such as fluorine\u201018 and copper\u201064, or based on new antagonist vector molecules. The advent of these innovations generates questions, such as which tracers can be used in clinical practice, how to compare scans performed with different tracers, or can antagonists be used to select patients for peptide receptor radionuclide therapy?
