Background null Gastric accommodation is an essential gastric motor function which occurs following ingestion of a meal. Impaired gastric fundic accommodation (IFA) is associated with dyspeptic symptoms. Gastric accommodation is mediated by the vagal pathway with several important physiologic factors such as duodenal nutrient feedback playing a significant role. IFA has been described as a pathophysiologic factor in several gastrointestinal disorders including functional dyspepsia, diabetic gast...

Abstract null null Background null Our purpose is to describe the structure, function and outcomes of our multidisciplinary pediatric thyroid program and to evaluate our experience in comparison to other high-volume centers. null null null Methods null We reviewed all thyroid operations performed 10/2012 through 09/2019, and examined number of cases per year, patient demographics, procedures, final diagnoses and results. Primary outcomes were hypoparathyroidism and recurrent laryngeal nerve (RLN...

OBJECTIVES To test the hypothesis that in dyspeptic children, prospective symptom severity following ingestion of a meal would correlate with percent gastric retention, and those ultimately diagnosed with gastroparesis would report worse symptoms. STUDY DESIGN Prospective, single center study with 104 children with dyspepsia completing a prospective dyspepsia symptom questionnaire before and after eating a standardized Tougas meal during gastric emptying scintigraphy (GES). Main outcomes include...

OBJECTIVE. The objective of our study was to compare the diagnostic performance of sequential 18F-FDG PET/MRI (PET/MRI) and 18F-FDG PET/CT (PET/CT) in a pediatric cohort with lymphoma for lesion detection, lesion classification, and disease staging; quantification of FDG uptake; and radiation dose. SUBJECTS AND METHODS. For this prospective study of 25 pediatric patients with lymphoma, 40 PET/CT and PET/MRI examinations were performed after a single-injection dual-time-point imaging protocol. Le...

419 Objectives PET/MRI offers the potential for anatomical and functional information in a single examination1. To reach its full potential, this technology will require robust attenuation correction (AC) algorithms2. The goal of this study was to compare the diagnostic accuracy of FDG-PET images of the brain processed according to MR-based AC (MRAC) with that of images obtained using traditional CT-based AC (CTAC). Methods IRB approval and informed consent were obtained for this study. All pati...
