#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.

#725 Contrast-Enhanced Ultrasonography (CEUS) Predicts the Effectiveness of Anti-Angiogenic Therapies in Patients with Liver Metastases from Neuroendocrine Tumors

Introduction: Liver metastases (LM) from neuroendocrine tumors (NETs) exhibit a typical hypervascular pattern in the arterial phase on CEUS, allowing for a differential diagnosis between NET and non-NET LM. Medical therapy includes agents acting on angiogenesis and vascularization which may result in a change in CEUS findings.

#724 Contrast-Enhanced Ultrasonography (CEUS) Reliably Predicts Tumor Progression in Pancreatic Neuroendocrine Tumors

Introduction: Neuroendocrine tumors (NETs) exhibit a typical vascular pattern in the arterial phase on CEUS. The role of CEUS in the prognostic evaluation of pancreatic NET (pNET) has been poorly investigated.

#163 Clinical value of MRI DWI and (Gd-EOB)-DTPA to assess liver involvement in patients with advanced gastroenteropancreatic neuroendocrine tumors (GEP-NETs)

Introduction: Standard MRI, including breath-hold techniques with SE T1 and T2 weighted images, biochemical shift, and 3D GRE and also T1 images after gadolinium enhancement Gd-DTPA, are useful in detecting liver lesions in patients with advanced GEP-NET. Recently, new algorithms of MRI, including diffusion-weighted imaging MRI (DWI) and i.v. (Gd-EOB)-DTPA (Primovist) contrast enhancement, seems to be promising in the detection of liver deposits.
