#3753 The additive value of F-18 fluorodeoxyglucose PET imaging in grade 1 gastroenteropancreatic neuroendocrine tumors (GEP-NETs)

Introduction: Grade 1 gastroenteropancreatic NETs (GEP-NETs) exhibit better prognosis compared to Grade 2-3 tumors. High uptake in 68Ga-DOTATOC PET imaging is commonly seen in well-differentiated tumors whereas uptake in F-18 FDG PET imaging is associated with aggressive behaviour.

#3524 Correlation of loss of ATRX expression with scintigraphic imaging studies in pancreatic neuroendocrine neoplasms

Introduction: Somatic inactivating mutations of ATRX (α thalassemia/mental retardation syndrome X-linked) in pancreatic neoplasms (pNENs) are associated with aggressive phenotype and are considered an independent prognostic factor of poor overall survival.

#2028 Education and Preparation for Nuclear Medicine Procedures in Neuroendocrine Tumor Patients

Introduction: In 2007, a coalition of health care organizations formed around the a unified goal of improving imaging safety and quality for adults (Image Wisely) and children (Image Gently). In 2008, the Society of Nuclear Medicine (SNMMI) joined this coalition, embracing its role in providing outreach to the patient community. The Society has created an annual patient program to reach patients and caregivers, and is continually seeking input from the patient community to improve the program and other online educational resources.

#1824 A Comparison of 68Ga-DOTA-TATE and 18F-FDG PET/CT Imaging on Patients with Pancreatic Neuroendocrine Neoplasm (pNEN)

Introduction: 68Ga-DOTA-TATE and 18F-FDG PET/CT are widely used for staging patients with pNEN.The sensitivity of nuclear modalities with pathologic correlation is unknown.

#834 Nuclear Imaging in Intermediate Grade Neuroendocrine Tumors

Introduction: Early diagnosis and grading is essential to the treatment decision-making in neuroendocrine tumors. Conventionally, proliferation rate (Ki-67) level is used for the grading of NET. Ga-68 SMS-R PET/CT is the imaging method of choice for the detection of unknown primary neuroendocrine tumors. It is very sensitive in well-differentiated tumors (Ki-67 < 2%). Poorly and undifferentiated tumors having Ki-67 greater than 20% are primarily responsible for false negativity of Ga-68 SMS-R PET/CT. In those patients, FDG-PET is performed to localize the site of the primary tumor.
