Correlation of 68Ga-DOTATATE and 18F-FDG PET/CT Uptake Parameters with PASS and GAPP Scores in Pheochromocytoma
Background: Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumors with highly variable biological behavior. Somatostatin receptor (SSTR)-based imaging with 68Ga-DOTATATE PET/CT has become an important functional imaging modality for evaluating these tumors. In contrast, 18F-FDG PET/CT reflects tum...
