<b>Background</b>: Prior studies have shown significant discrepancy between the initial radiologist and pediatric radiologist interpretation of imaging exams performed on pediatric patients. Studies specifically focused on the rate of discrepancy of ultrasound (US) exams for suspected appendicitis and intussusception are deficient. <b>Objective:</b> To determine the agreement and discrepancy rates, and the clinical impact of discrepancies in the diagnosis of appendicitis and ileocolic intussusception between initial US performed at referring community hospitals and second (2^nd) opinion US performed at an academic pediatric tertiary care hospital.

In paediatric nuclear medicine the majority of the scans require intravenous (IV) access to deliver the radiotracers. Children and parents often cite procedural pain as the most distressing part of their child’s hospitalization. In our department, various pain management strategies including physical and psychological distraction methods and pharmacological intervention have been implemented for the reduction of procedural pain. The purpose of this study was to evaluate and compare different pain reduction strategies used in the paediatric Nuclear Medicine department. Read More

Despite being recognized as a secondary sign of appendicitis, no clear definition exists about the amount of intra-abdominal fluid considered physiologic in children. The purpose is (1) to assess the amount of intra-abdominal free fluid by US and MRI in children with suspected appendicitis, (2) to detect the performance characteristics of US for detecting free fluid, and (3) to determine the association between fluid volume and perforated appendicitis. An additional ex-vivo study was done to assess the validity of US measurement abdominal free fluid volume using phantoms. Read More

Scoliosis is a complex spine deformity with direct functional and cosmetic impacts on the individual. The reference standard for assessing scoliosis severity is the Cobb angle which is measured on radiographs by human specialists, carrying interobserver variability and inaccuracy of measurements. These limitations may result in lack of timely referral for management at a time the scoliotic deformity progression can be saved from surgery. We aimed to create a machine learning (ML) model for automatic calculation of Cobb angles on 3-foot standing spine radiographs of children and adolescents with clinical suspicion of scoliosis (AIS) across two clinical scenarios (idiopathic, group 1 and congenital scoliosis, group 2).
