#3825 Ga-68 DOTA-TOC PET/CT uptake by the parathyroid glands in patients with multiple endocrine neoplasia type 1 (MEN1)

Introduction: Primary hyperparathyroidism (PHPT) is the most common manifestation of MEN1. While Ga-68 DOTA-TOC PET/CT (GaPET) is increasingly used in this cohort for assessment of neuroendocrine tumors (NETs), there are limited data on its utility in assessing parathyroid disease.

#3817 Mid-treatment response to 177Lu-DOTATATE – A possible estimate for final outcome in patients with neuroendocrine neoplasms

Introduction: Patients with advanced or unresectable neuroendocrine neoplasm (NENs) have limited systemic treatment modalities. Among the patients receiving peptide receptor radionuclide therapy (PRRT) treatment with 177Lu-DOTATATE, a subset will require further chemotherapy in later stages. Hence, limiting radiation exposure is of paramount importance. However, there are no mid-term predictive factors for response to PRRT.

#3730 Somatostatin receptor expression in lung neuroendocrine tumors – An analysis of Dotatate PET scans

Introduction: Somatostatin receptor (SSTR) expression in metastatic lung neuroendocrine (carcinoid) tumors has not been well-characterized using modern positron emission tomography (PET) imaging. Understanding the degree and uniformity of SSTR expression is important to establish the role of SSTR-targeted treatments, including peptide receptor radiotherapy (PRRT), in lung NETs.

#3378 Clinical impact of 68 GA DOTANOC PET CT and 18 F FDG PET CT in clinical management of WHO Grade 2 neuroendocrine tumors

Introduction: WHO well differentiated grade 2 NET is large subgroup with extensive tumor heterogeneity. Both FDG and DOTA PET CT are influential in the management of NET. We determine the clinical impact of dual tracer imaging in grade 2 NET.

#3324 Elastographic localization of insulinoma

Introduction: A 15-year-old healthy female, initially admitted with less serious signs of hypoglycemia. Laboratory studies showed a glucose concentration of 1.2 mmol/l and insulin 9.6 μU/ml. Complete blood count, basal metabolic profile, activity of C - reactive protein and urine drug screen, were unremarkable. Fasting test confirmed biochemical signs of insulinoma.
