#3857 The use of quantitative contrast-enhanced endoscopic ultrasound in the evaluation of pancreatic neuroendocrine tumors – Can we move from quality to quantity? A proof-of-concept study

Introduction: Contrast-enhanced EUS (CE-EUS) is a helpful tool for the diagnosis of pancreatic focal lesions, as pancreatic cancer (PC) and pancreatic neuroendocrine tumor (pNEN). The enhancement of the lesion after contrast medium injection is usually assessed qualitatively and arbitrarily by the endosonographer. Dedicated software has recently been developed to obtain an unbiased quantitative assessment using perfusion parameters.

#3855 Contrast-enhanced and tissue harmonic endoscopic ultrasound for pancreatic neuroendocrine tumor diagnostic

Introduction: Endoscopic ultrasonography (EUS) is an examination using ultrasound and an endoscopic device, designed to image digestive tract and adjacent organs. The combination of tissue harmonic endoscopic imaging (THI) and contrast enhancement (CE) expands its diagnostic and imaging capabilities.

#3581 Pancreatic neuroendocrine tumors (PanNETs) vascularization: From “micro” to “macro”

Introduction: Density of microvessels in pancreatic neuroendocrine tumors (PanNETs) changes according to their biological behaviour. Differently from other non-neuroendocrine cancers, a low microvessel density (L-MVD) is associated with higher disease aggressiveness and poorer prognosis.

#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.

#2113 How to Perform Contrast Enhanced Oncologic Staging MRI of Abdomen and Pelvis with a Hepatocyte Specific Agent in a Large Bore MR Scanner: Optimizing Extrahepatic Tumor Evaluation in Neuroendocrine Neoplasms

Introduction: Liver specific MR contrast agents in neuroendocrine neoplasms (NEN) have shown its advantages in evaluation of hepatic tumor burden. However, a standard scan protocol is insufficient in extrahepatic and especially pelvic tumor evaluation.
