#2990 Pitfalls in Glucagon-Like Peptide-1 Receptor Imaging

Introduction: Physiological pancreatico-duodenal DOTA-Exendin-4 uptake in the Brunner’s glands of the proximal duodenum occurs in Glucagon-like peptide-1 receptor (GLP-1R) imaging and is a known potential pitfall.

#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.

#1870 Detection of Metastatic Insulinoma with 68Ga-NODAGA-Exendin-4 PET/CT in a Young Child – A Case Report

Introduction: Malignant insulinomas are extremely rare in children. Localizing metastases of insulinoma is challenging. Imaging modalities like CT and MRI show limited results. Somatostatin-receptor (SSTR) imaging (SRS) performs better. However, a subgroup of malignant insulinoma lack SSRT-2 and can, therefore, not be localized using SRS. We propose that in these cases GLP-1R imaging, using the stable GLP-1 analog exendin, could play an important role.
