Gastric outlet obstruction in neonates and infants is an uncommon condition that results in nausea, non-bilious vomiting, and abdominal distension. Comprehension of the disease entities of obstructed gastric outlet can help radiologists make accurate diagnoses and guide management. The purpose of this educational exhibition is to provide a review of radiographic findings of the differential diagnosis of gastric outlet obstruction and its clinical manifestations. Read More

Ultrasound is the most accessible and reliable modality to evaluate the kidneys in neonates and young infants. The sonographic appearance of the kidneys in the immediate postnatal period can differ significantly from that in older children and adults. In clinical practice, radiologists encounter a full spectrum of renal pathology, with some appearing as hyperechogenicity on ultrasound. The purpose of this case-based educational exhibit is to provide a review of normal and abnormal causes of increased echogenicity of the kidneys in neonates and young infants, and common sonographic pitfalls that can artificially increase renal echogenicity Read More

Pediatric acute appendicitis is the most common surgically treated disease in the United States. Evaluation via ultrasonography is recommended as the most appropriate initial modality to diagnose acute appendicitis in the pediatric population by the American College of Radiology. However, nonvisualization of the appendix creates diagnostic challenges leading to additional imaging and laboratory studies as well as costs. The purpose of this study is to determine the value of identifying the ileocecal valve as a reliable initial landmark for identification of the appendix via ultrasonography. Read More
