Edotreotide gallium Ga-68 is indicated for localizing somatostatin receptor positive neuroendocrine tumors by positron emission tomography. [Dotatate gallium Ga-68] is used for a similar indication. Dotatate gallium Ga-68 has lower tumor uptake but this data is highly variable between patients.  Edotreotide gallium Ga-68 was granted FDA approval on 21 August 2019."}]
