Key terms
Gallium Ga-68 dotatate is a radioactive imaging tracer that targets somatostatin receptors. NETSPOT supports PET localization of certain neuroendocrine tumors.
Dotatate binds somatostatin receptors, particularly subtype 2. Gallium-68 emits a signal detected by positron-emission tomography, allowing clinicians to map receptor-bearing tissue. This tracer is used to locate disease; it is not the same medicine as lutetium-177 dotatate, which delivers therapeutic radiation despite sharing a targeting component. Product label.
Evidence limits
How to read the evidence
Diagnostic accuracy depends on receptor expression, reference standards, and the population selected for imaging. The supporting studies were relatively small and often single-center. Neither a positive scan nor the word peptide establishes malignancy by itself, and imaging results should not be treated as a stand-alone treatment decision. Product-specific scope.
