RESUMO
Pheochromocytomas/paragangliomas are somatostatin receptor 2-overexpressing tumors. Ga-DOTA-peptide imaging has recently shown excellent results in the detection of metastatic lesions in these tumors. However, currently used Ga-DOTA peptides show different somatostatin receptor affinities. Here, we report the remarkable differences in a patient who was imaged with Ga-DOTANOC and Ga-DOTATATE PET/CT within a 7-month period. The patient presented with a nearly negative Ga-DOTANOC PET/CT scan, whereas on Ga-DOTATATE PET/CT, multiple highly positive lesions were identified.
