Nutritional deficiencies in children are prevalent both in the US and abroad often under-diagnosed unless symptomatic. Some nutritional deficiencies have conspicuous imaging findings that might help with diagnosis and/or follow up in a timely manner. Similarly, imaging might be needed to diagnose or follow complications related to malnutrition and eating disorders such as bulimia, anorexia nervosa, binge eating and pica. This educational exhibit will review radiographic, CT and MR imaging of nutritional deficiencies and complications of malnutrition and eating disorders in children Read More

Ultrasound has become a powerful tool for the evaluation of bowel pathology in the children. In the newborn, ultrasound (US) can be used to diagnose, stage, and follow up necrotizing enterocolitis (NEC) and its complication. US has excellent sensitivity and specificity for the identification of bowel wall thickening, peristalsis, pneumatosis, portal venous gas and free air and has become an integral evaluation tool for the newborn with abdominal distention. Our educational poster will: 1. Summarize proper US equipment, technique and protocol for diagnosing and following up NEC 2. Discuss advantages and benefits of incorporating US in the evaluation of bowel in newborns 3. Illustrate the sonographic findings of mild, moderate and severe NEC through cases Read More

Muscle hernias occur when a muscle protrudes through a fascial defect into the subcutaneous fat, hence presenting as a subcutaneous palpable mass. While the palpable abnormality is usually asymptomatic, it can also present with pain. Muscles hernias occur most often in adolescents and young adults and might be due to sporting activities, trauma, or overlying fascia weakness. Because of its dynamic real-time imaging capabilities, ultrasound is best suited for the evaluation of these lesions. Moreover, a definitive diagnosis can be reached with ultrasound hence avoding additional time and expenses while promptly providing reassurance to the patients and families. US has excellent sensitivity and specificity for the identification of muscles hernias. However, baseline knowledge of this disease as well as close attention to technique are needed to reliably reach the proper diagnosis. Our educational poster will: 1. Summarize proper US equipment, technique and protocol for diagnosing muscle hernia 2. Discuss advantages and benefits of US over other imaging modalities 3. Illustrate the sonographic findings of muscles hernias Read More

Renal artery stenosis (RAS) is an important cause of hypertension in children. When suspected, imaging options include Doppler US, CTA and MRA. However, conventional angiography remains the gold standard. We investigate the accuracy and inter-reader reliability of CTA in children with suspected renal artery stenosis. Read More

CT can be a powerful tool for the evaluation of the chest and abdominal pathology in children. While not as commonly used as in the USA, CT studies represented approximately 15% of cases received from low- and lower-middle income Countries for expert second opinion by a pediatric radiologist in the WFPI teleradiology platform, over the last 4 years. This pictorial review lists the indications, details the technical parameters, and exemplifies imaging findings of CT studies from this setting. Read More

One of the pillars of the American College of Radiology initiative Imaging 3.0 is patient engagement. However, there are no specific guidelines into which interventions should be prioritize in order to maximize the benefits while acknowledging finite resources. We conducted this study to understand families’ preferences for communication before, during, and after receiving pediatric radiology services. Read More

Dynamic Airway CT (DACT) has risen in popularity in recent years, however, studies of Tracheobronchomalacia (TBM) are hindered by inconsistent definitions which variously rely on airway area, airway diameter, and qualitative measures. We explore the interrater reliability of these measures. Read More

Assessment of fluid overload in hemodialysis patients is usually based on a patient’s ideal weight which presents a challenge, especially in children due to normal growth and development. Noninvasive, validated sonographic fluid balance measurements could potentially guide fluid removal in children undergoing hemodialysis. We examine changes in IVC diameter and lung b-lines in children pre- and post- dialysis. Read More

Volume overload is linked to increased cardiovascular morbidity and mortality in children receiving hemodialysis (HD). Clinician assessment of volume status lacks accuracy and has substantial inter- and intra- observer variability. We investigated the use of ultrasound (US) skin thickness, and muscle elastography in pediatric HD patients. Read More
