#491 International Survey for the Use of Biomarkers and Molecular Imaging in Neuroendocrine Tumors (NET): What we are Using in Daily Practice
Introduction: Several guidelines have given recommendations for optimal use of biomarkers and molecular imaging. However, those guidelines’ implementation may not be always possible due to local policies or lack of access to several diagnostic studies.

#863 Assessment of Neuroendocrine Tumors' Heterogeneity with Combination of Molecular Imaging Studies
Introduction: Neuroendocrine tumors (NET) are heterogeneous neoplasms. The choice of the appropriate molecular imaging study for assessment of disease extent usually depends on tumor grade.

#477 Glucagon-Like Peptide 1 Receptor (GLP-1R) Imaging for the Preoperative Localization of Benign Insulinomas in 30 Patients
Introduction: Biochemical diagnosis of endogenous hyperinsulinemic hypoglycemia is straightforward. Surgical removal of an insulinoma is hampered by difficulties to localize it using conventional radiological procedures. In vitro data suggest that human insulinoma cells exhibit a high density of GLP-1R. 111In-exendin-4 is an 111In labeled GLP-1R agonist that binds with high affinity to GLP-1R and may be helpful in localizing insulinomas.

#1330 Pancreatic Neuroendocrine Neoplasms: Magnetic Resonance Imaging Features and Correlation with Their Histological Grade
Introduction: Pancreatic neuroendocrine neoplasms (PanNENs) have different biological behavior and prognosis according to their histological grade. At present, few data are available regarding the value of imaging techniques in predicting the grade of PanNENs.

#2003 Comparison of Glucagon-Like-Peptide-1 (GLP-1) Receptor PET/CT, SPECT/CT and 3T MRI for the Localisation of Insulinomas: Evaluation of Accuracy in a Prospective Crossover Imaging Study
Introduction: Benign insulinomas are the most prevalent cause of endogenous hyperinsulinaemic hypoglycaemia (EHH) in adults and due to their small size difficult to localise.

#225 New Imaging Modalities in the Diagnosis of Phaeochromocytoma
Introduction: Phaechromocytoma are uncommon chromaffin cell tumors of the adrenal medulla. The diagnostic assessment includes various radiological localizing techniques, including somatostatin based scintigraphy.

#834 Nuclear Imaging in Intermediate Grade Neuroendocrine Tumors
Introduction: Early diagnosis and grading is essential to the treatment decision-making in neuroendocrine tumors. Conventionally, proliferation rate (Ki-67) level is used for the grading of NET. Ga-68 SMS-R PET/CT is the imaging method of choice for the detection of unknown primary neuroendocrine tumors. It is very sensitive in well-differentiated tumors (Ki-67 < 2%). Poorly and undifferentiated tumors having Ki-67 greater than 20% are primarily responsible for false negativity of Ga-68 SMS-R PET/CT. In those patients, FDG-PET is performed to localize the site of the primary tumor.

#1457 Small and Large Incidental Non-Hyperfunctiong Pancreatic Neuroendocrine Tumors: Spectrum of Magnetic Resonance Imaging Features
Introduction: The improvement of imaging techniques significantly increased the detection of small incidental non-hyperfunctioning pancreatic neuroendocrine neoplasms (NF-PanNENs). Most NF-PanNENs <2 cm are likely benign lesions and a non-operative approach could be advocated in selected cases for these lesions.

#1650 Lung Carcinoid: Role of NSE and Imaging Techniques in Long-Term Follow-Up of Malignancy Recurrence
Introduction: Typical and atypical Lung Carcinoids (LC) are rare neuroendocrine tumors usually characterized by good prognosis. Malignancy recurrence (MR) is uncommon but may occur even after several years; a close long-term follow-up is required.
