#946 Immunohistochemical Staining of Catecholamine-Synthesizing Enzymes in Head and Neck Paraganglioma Tissue

Introduction: Head and neck paragangliomas (HNPGLs) are non-producing neuroendocrine tumors, alhough 19-28% of patients have an increased dopamine production. The high sensitivity of 18F-DOPA PET also shows that these tumors might be able to synthesize catecholamines.

#760 Intraoperative Gamma Probe Detection of Metastatic Medullary Thyroid Carcinoma (MTC) with 111In-Pentetreotide

Introduction: MTC is a rare thyroid malignancy representing approximately 5-10% of all thyroid tumors. Early diagnosis and radical surgery are essential to reduce the morbidity and mortality associated with MTC. Somatostatin receptors (SSTRs) expression has been described in MTC with a variable pattern, SSTR2 being prevalent. Although somatostatin analogues demonstrated poor efficacy in the control of MTC growth, SSTR expression can be useful in Nuclear Medicine diagnostic procedures. 111In-pentetreotide scintigraphy and 68Ga-somatostatin analogues PET-CT represent valuable techniques in the detection of MTC, although with a lower sensitivity compared to 18F-DOPA PET-CT.

#651 Additional Value of New Molecular Imaging Tracers in the Detection of Recurrent/Residual Disease in Patients with Neuroendocrine Tumors

Introduction: Recent studies have proposed new molecular imaging tracers, such as 18F-DOPA and 68Ga-DOTANOC, for the detection of recurrent/residual neuroendocrine tumors (NET) in case of negative conventional imaging modalities.

#351 Comparison of 68Ga-Somatostatin Analogues, 18F-DOPA and 18F-FDG PET/CT in Patients with Recurrent Medullary Thyroid Carcinoma

Introduction: Early detection of recurrences is a crucial step in the management of patients (pts) with medullary thyroid carcinoma (MTC). Currently, there is growing interest for PET tracers in MTC such as: 18F-FDG (reflecting glucose metabolism), 18F-DOPA (reflecting amine decarboxylation), 68Ga-somatostatin analogues (reflecting somatostatin receptors expression)

#201 Comparison of 18F-DOPA, 68Ga-Somatostatin Analogues and 18F-FDG PET-CT in Patients with Recurrent Medullary Thyroid Carcinoma

Introduction: Various PET tracers have been proposed for detection of recurrent disease in medullary thyroid carcinoma (MTC). No data have been reported comparing 18F-DOPA and 68Ga-somatostin analogues (SA) in MTC.
