    Abstract:
    Molecular imaging of the somatostatin receptor plays a key role in the clinical management of neuroendocrine tumors. PET imaging with somatostatin analogs (SSAs) labeled with 68Ga or 64Cu is currently the gold standard in clinical practice. However, widespread implementation of 68Ga imaging is often hampered by practical and economic issues related to 68Ge/68Ga generators. 18F offers several advantages to tackle these issues. Recent developments in radiochemistry have allowed a shift from 68Ga toward 18F labeling, leading to promising clinical translations of 18F-labeled SSAs, such as Gluc-Lys-[18F]FP-TOCA, [18F]F-FET-βAG-TOCA, [18F]AlF-NOTA-octreotide, [18F]SiTATE, and [18F]AlF-NOTA-JR11. This review gives an update of currently available clinical data regarding 18F-labeled SSA tracers and provides justification for the clinical application of this class of tracers.
