SST and paraganglioma: The introduction of somatostatin (SST)-receptor imaging agents (e.g. 68GaDOTA-TOC, 68Ga-DOTA-TATE) and combined functional/anatomical imaging (PET/CT) led to a dramatic improvement in detecting head and neck paragangliomas (HNPGL) and comparing radioisotopes 123I-MIBG and 18F-DOPA to this SST-analogue, 68Ga-DOTA-TOC appears to be the best choice in the detection of both, malignant and non-malignant HNPGL [21–26].
