#4387 Exenatide-test for diagnosing endogenous hyperinsulinemic hypoglycaemia: A randomised placebo-controlled cross-over proof-of-principle study – FAST study

Introduction: The gold standard to diagnose endogenous hyperinsulinemic hypoglycaemia (EHH) is the fasting test which is cumbersome and incurs high costs. In the setting of radio-labelled 68Ga-exendin-4 PET/CT in patients with EHH (to localise insulinoma), we unexpectedly observed clinically relevant hypoglycaemia following administration of the tracer, which does usually not occur after GLP-1 agonist therapy in type 2 diabetic patients and in healthy subjects.

#4327 Metastatic non-functional pancreatic neuroendocrine tumour with transformation to insulinoma shown on 68Ga-Exendin-4 PET/CT

Introduction: 68Ga-exendin-4 PET/CT imaging has been utilised for benign insulinomas. However, some reports demonstrated the absence of GLP-1R expression of malignant insulinomas.

#4323 The value of 68Ga-Exendin-4 PET/CT for benign and metastatic insulinoma

Introduction: Insulinoma is the most common functional pancreatic neuroendocrine tumour which is difficult to locate by conventional imaging. 68Ga-exendin-4 PET/CT is a promising technique for detecting benign insulinomas but is not definite for metastatic insulinomas.

#3947 Heterogeneity of multiple pancreatic neuroendocrine tumors identified by 68Ga-DOTANOC and 68Ga-exendin-4 PET/CT in a patient with endogenous hyperinsulinemic hypoglycaemia and multiple endocrine neoplasia 1

Introduction: Insulinomas are the most frequent functional neuroendocrine tumors of pancreas cause endogenous hyperinsulinemic hypoglycemia (EHH). In about 10% cases, insulinomas are associated with multiple endocrine neoplasia 1 (MEN1).
