4D Ultrasound High Definition Flow with Spatio-Temporal Image Correlation in Evaluation of Neuroendocrine Liver Metastases – Preliminary Study Abstract #2184

Introduction: 4D Ultrasound technology merging Power Doppler option called High Definition Flow (HDF) with Spatio-Temporal Image Correlation (STIC) is used in gynecology and obstetrics. It seems to be a promising tool in assessing tissue vascularization.
Aim(s): To assess whether HDF STIC technique could be a useful tool for evaluation of gastro-entero-pancreatic neuroendocrine neoplasms (GEP-NENs) advancement.
Materials and methods: Forty-eight patients (mean age 57.7(+/-10.3) years; male 40.9% (n=18)) diagnosed with metastatic GEP-NENs were included to analysis. All subjects were enrolled in the Department of Endocrinology and Neuroendocrine Tumors, Medical University of Silesia, Katowice. We analyzed liver metastases. Patients with G3 grading or faintly vascularized lesions were excluded. HDF STIC volumes were acquired during USG examination. 4D indices (Volumetric Pulsatility Index (vPI) and Volumetric Systolic/Diastolic Index (vS/D)) were calculated using dedicated software.

Introduction: Neuroendocrine neoplasms are divided into well-differentiated neuroendocrine tumors (WDNETs) and poorly differentiated neuroendocrine carcinomas (PDNECs).The correlation between Gastroenteropancreatic Neuroendocrine Neoplasms (GEPNENs) and immunocheck point molecule-PD-L1 is still unclear now.

Introduction: Liver metastasis (LM) are very frequent (65-95%) and represent a crucial prognostic factor in patients with gastroenteropancreatic neuroendocrine neoplasms (GEP NENs). The paucity of relevant experimental models has limited the understanding of the pathophysiology of NENs and the development of efficient therapeutic strategies

#76 Role of contrast-enhanced ultrasonography in the differential diagnosis of the pancreatic and hepatic lesions
Introduction: Contrast-enhanced ultrasonography (CEUS) is a new promising tool for the characterization of pancreatic lesions. This technique allows for highlighting the micro-vascularization of a lesion, especially with the use of second generation contrast media, characterized by harmonic responses at low acoustic pressures. Pancreatic endocrine tumors (PET)s were reported to have a peculiar behavior at CEUS, consisting of a higher enhancement compared to normal pancreas in the arterial phase and a rapid washout.
