In this study, we trained two convolutional neural networks to automatically identify the third vertebral level and segment the abdominal muscle in contrast enhanced abdominal CT images. In the future, these models will be used to determine reference ranges for skeletal muscle mass in children by age for the purpose of identifying patient characteristics associated with differences in skeletal muscle mass.

Radiologic diagnosis of rib fractures in suspected infant abuse is often challenging, and costochondral junction (CCJ) rib fractures can be particularly problematic. In an effort to enhance diagnostic accuracy and dating, we studied the dynamic radiologic spectrum of CCJ rib fractures on serial skeletal surveys (SSs). Read More

Prior to maturity, a secondary physis surrounding the patella defines an area of potential weakness. We seek to understand how age, sex, and physeal status affect the prevalence and degree of patellar osteochondral injury and medial patellofemoral ligament (MPFL) injury after acute patellar dislocation.

Bassett's ligament is an accessory fascicle of the anterior tibiofibular ligament that is not well addressed in pediatric patients. In the adult literature, it is known that the ligament is not present in some patients, but may be thickened in the setting of talar dome osteoarthritis. The purpose of our study was to determine the prevalence of Bassett’s ligament and measure its thickness in pediatric patients with MRI findings of lateral talar osteochondral lesions (OCLs), medial talar OCLs, and posterior ankle impingement and compare these measurements with patients with a normal ankle MRI.

Scaphoid fractures are well-recognized in adults where delayed diagnosis and treatment of displaced or rotated fragments can produce avascular necrosis and long-term morbidity. In children, scaphoid fractures are uncommon, particularly in the skeletally immature, with an estimated incidence of 11 per 100,000, and there is a relative paucity of published literature on its imaging characteristics and clinical prognosis. Therefore, the purpose of this study was to investigate imaging findings, fracture locations, and the clinical outcomes of scaphoid fractures in pre-teen children. Read More

Imaging during the evaluation of suspected child abuse victims may be requested 24 hours a day, however, pediatric radiologists may not always be available to interpret these studies. Timely reporting is important for treatment and disposition in this vulnerable population. In addition, the accuracy of detection of subtle injuries is critical for patient safety. The current protocol at our institution consists of an immediate preliminary interpretation by an adult radiologist when a skeletal survey is obtained after hours, and final interpretation by one of three pediatric radiologists during normal business hours.

Solitary epiphyseal lesions are rare in children, and no large series describes the relative frequency of different etiologies. Understanding the incidence and nature of epiphyseal lesions is critical in informing radiologists encountering these lesions. Read More

Several organizations have recommended ultrasound (US) screening for Developmental Dysplasia of the Hip (DDH) in infants with risk factors to facilitate early detection and treatment of the disease, and mitigate long-term morbidity. However, there is still debate on the value of screening US, particularly the dynamic stress component. The goal of our study was to evaluate the predictive value of selective screening hip US of infants with risk factors for detection of DDH requiring treatment, including the value of dynamic stress imaging.
