<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.

Fetal anemia is a severe condition with diverse etiologies that can lead to complications, including fetal hypoxia, heart failure, hydrops fetalis and intrauterine fetal death if left untreated. In severe cases, intrauterine transfusion (IUT) is a life-saving intervention. The impact of fetal anemia on brain development remains unclear. This study aimed to evaluate neuroimaging findings in fetuses diagnosed with anemia using magnetic resonance imaging (MRI). Read More

Pediatric thyroid carcinoma (PTC) is associated with higher rates of regional and lung metastases and a greater recurrence rate, though it maintains an excellent overall prognosis. While the diffuse sclerosing variant of PTC (DSV-PTC) is a rare subtype, it is disproportionately observed in the pediatric population. Ultrasound findings of DSV-PTC can include a thyroid nodule or diffuse thyroid enlargement, heterogeneous hypoechogenicity, and diffuse microcalcifications. It often presents with extensive cervical lymph node metastasis and more advanced disease at the time of diagnosis, which is linked to a higher recurrence risk. However, a comprehensive description of the sonographic features of DSV-PTC within a large pediatric cohort is currently lacking. This exhibit aims to address the current knowledge gap by illustrating the spectrum of sonographic findings for DSV-PTC in a pediatric population and describing its common associated imaging features.

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

Diffuse thyroid disease (DTD) encompasses a spectrum of thyroid disorders, including autoimmune conditions such as Hashimoto's thyroiditis (HT). The association between HT and thyroid carcinoma remains controversial. Particularly in children, a robust, large-scale investigation is lacking, and the nature of this potential correlation and outcomes remains poorly elucidated. The aim of this study is to evaluate the US features of the thyroid gland and cervical lymph nodes, the clinical characteristics and outcomes of pediatric patients with DTD and thyroid carcinoma (TC).

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).

This study explored whether background 18F-FDG uptake differs between pediatric sarcoma cases (patients who underwent PET-CT as part of their clinical evaluation, at diagnosis, or during treatment) and non-oncologic NF-1 controls, reflecting possible systemic metabolic changes in cases that might distinguish tissues in this group from corresponding tissues in controls.
