[18F]SiTATE PET for PRRT selection and monitoring metastatic tumors of the adrenal medulla and extra-adrenal paraganglia

In metastatic PPGL, [¹⁸F]SiTATE effectively visualizes tumor burden and supports patient selection and response assessment for PRRT. Notably, the data revealed a heterogenous response across PET-based, CT-based, and biochemical assessments. The underlying mechanisms of these discrepancies remain unclear and warrant further investigation.
