#2798 Risk of Pre-Operative Understaging of Duodenal Neuroendocrine Tumors at Conventional Imaging: When Surgery Becomes the First Choice

Introduction: Duodenal neuroendocrine neoplasms (dNENs) are heterogeneous tumors that can exhibit aggressive behavior, with loco-regional nodes and distant metastases. Pre-treatment staging is the basis for planning either surgical or endoscopic treatment.

#2242 Diagnostic Utility of Ki-67 as a Mean to Predict the Uptake of Functional Imaging Modalities in Patients with Neuroendocrine Neoplasms

Introduction: Functional imaging with FDG-PET and somatostatin receptors scintigraphy (SRS), play a key role in the diagnosis, treatment and follow-up of patients with neuroendocrine neoplasms (NENs). The proliferative index, ki67, is a reliable pathological marker for grading.

#2185 Nonfunctional Pancreatic Neuroendocrine Tumor (NF PNET) Imaging and Evaluation Using 18F-FDG and 68Ga- DOTANOC-PET/CT: Initial Data of a Prospective Study

Introduction: Predicting aggressive behavior of NF PNET still remains controversial. It is known that lymph node metastases are rare but possible also on small (1-2 cm) NF-PNET. Positive 18F-FDG-PET/CT avidity is associated with poor prognosis in NETs.

#1826 An Intrapatient Comparison of 18FDG And 68Ga-DOTA-TATE PET/CT Imaging in Patients with Gastrointestinal Neuroendocrine Neoplasm

Introduction: 18FDG-PET/CT was the most widely used functional imaging for cancer, while 68Ga-DOTA-TATE PET/CT could evaluate the SSTR expression of NEN.

#1340 Analysis of 18FDG-PET/CT in Patients with Pancreatic Neuroendocrine Tumor

Introduction: Neuroendocrine Tumor (pNET) comprised a wide and heterogeneous group of neoplasms. 18FDG-PET/CT was the most widely used functional imaging for cancer in general and had a high accuracy for poorly differentiated NENs.
