Vaping associated pulmonary injury (VAPI) has recently received national attention as an epidemic resulting in cases of significant morbidity and mortality from electronic cigarette use. The purpose is to present the clinical and imaging findings in adolescents with pulmonary symptoms from suspected VAPI. 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

The anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitides (AAV) are a group of autoimmune diseases characterized by vascular inflammation requiring immunosuppressive treatment. Involvement is most common of the kidneys and lungs, although there is a paucity of literature reporting the chest imaging findings in children. Our goal is to describe the salient chest imaging findings of pediatric AAV to promote recognition by radiologists. Read More

At our institution, airway radiographs are routinely checked by the radiologist to ensure diagnostic image quality prior to the technologist completing the examination. These checks interrupt the workflow for both the technologist and radiologist. In this study, we develop and validate a deep learning algorithm to detect non-diagnostic lateral airway radiographs.

Children’s interstitial lung diseases (chILD) comprise a large spectrum of rare diffuse lung disorders, with a subset of patients developing chronic fibrosing lung disease. While imaging criteria for lung fibrosis are established for adults and correlate with prognosis and outcome, there are limited data on imaging for diagnosis, prognosis, and outcomes in children with fibrotic lung disease. To fill this gap, a group of ILD specialists aimed to define the imaging features for diagnosis of lung fibrosis for a forthcoming randomized trial of nintedanib versus placebo in pediatric patients with fibrosing ILD (1199-0337; NCT04093024).

Tracheomalacia (TM) is a common morbidity associated with prematurity and manifests as dynamic collapse of the trachea lumen due to cyclic changes of intrathoracic pressure during breathing. Premature infants often have elevated work of breathing (WOB) related to their distal, small airway and lung abnormalities. The large airway contribution to WOB can be determined using computational fluid dynamics (CFD), which is a well-known technique to calculate the resistance and WOB in the human airway. However, previous studies are based on static airway geometry without motion. Using the novel technique of ultrashort echo time (UTE) magnetic resonance imaging (MRI), the tidal volume and airway motion can be used to create a dynamic model for use in CFD. Our aim is to calculate the estimated WOB in a dynamic trachea with neonatal TM compared with a stable, static trachea.

Small airways disease (SAD) is a common pathology seen in pediatric patients. In suspected cases of SAD/RSV/bronchiolitis, chest radiographs are often ordered to diagnose disease and to rule out other conditions, such as bacterial pneumonia. While SAD and pneumonia have unique radiographic features, the threshold to diagnose such findings may depend on radiologist experience and training background. The purpose of this study is to investigate intra-radiologist precision and accuracy in diagnosing normal, SAD, and bacterial pneumonia on pediatric chest radiography. Read More
