Ileocolic intussusception is a common cause of intestinal obstruction in young children. Most patients undergo image-guided enema reduction followed by a surgical reduction in enema fails. Many factors associated with decreased enema success have been described in the literature, although a concise scoring system to identify patients who are at risk for surgical intervention and complications does not exist. The goal of this project was to develop a scoring system to identify patients who are at increased risk for enema failure and surgical complications. Read More

Authors: Patel Dhruv, Loewen Jonathan, Richer Edward

Keywords: Ileocolic Intussusception, Image guided therapeutic enema

Determine if a simple scoring system can accurately predict the reducibility of ileocolic intussusceptions with therapeutic enema, and eventual surgical outcomes in those patients failing reduction. Read More

Authors: Richer Edward, Patel Dhruv, Braithwaite Kiery, Milla Sarah, Loewen Jonathan

Keywords: Intussusception, ultrasound

Determine if the length of time between diagnosis of an intussusception and therapeutic enema, or reported length of symptoms, is associated with lower enema success rates or higher rates of complicated surgery and bowel resection. Read More

Demonstrate how a pediatric radiology division at a single institution structures short-interval feedback to residents. Describe how the division collects interval resident feedback. Demonstrate resident responses to this pilot program of instituting standardized weekly feedback. Read More

A trend of increased utilization of pediatric breast ultrasound has been suggested in our pediatric healthcare system. Despite this perceived increase in cases, the number of concerning breast findings in our population remains extremely low. Our hypothesis is that there has been significant increase in the number of pediatric breast ultrasounds, yet examinations remain overwhelmingly benign. Read More

Idiopathic thickening of the pyloric muscle can occur in young infants, causing projectile vomiting, electrolyte abnormalities, and necessity for surgical intervention to relieve the gastric outlet obstruction. Case reports have been published describing infants with HPS who also have portal venous gas (PVG) visualized within the liver. The presence of PVG in other clinical scenarios often indicates a severe and potentially life threatening bowel condition. The purpose of this study was to determine the incidence of infants with hypertrophic pyloric stenosis (HPS) and concurrent portal venous gas (PVG), as well as whether there are unique clinical features or different outcomes in the HPS patients with PVG versus without PVG.

Pediatric stomach tumors encompass a broad range of pathologies. These tumors are rare in the pediatric and adolescent population and can be easily misdiagnosed. In addition, approach to imaging diagnosis in this population may differ from adults. In this educational exhibit, we will focus on stomach tumors. This exhibit will provide viewers with: 1. A visual differential diagnosis of common and uncommon tumors in each section of the stomach with a focus on multi-modality imaging. 2. Review of common imaging findings for each tumor, highlighting high-yield characteristic findings of each. 3. Key findings and tips that can help the practicing radiologist differentiated between benign and malignant tumors. Read More
