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

The mucopolysaccharoidoses are a varied group of lysosomal storage diseases, uncommon in the general population. The accumulation of gylcosaminoglycans throughout the patient’s body leads to a variety of clinical and imaging manifestations. The osseous finding of these patients are well documented on radiography; however, to our knowledge, the soft tissue imaging findings of these patients have not been previously described. Therefore, the aim of this educational exhibit is to elucidate the soft tissue imaging findings of large joints, focusing on patients with Mucopolysaccharoidsis Type I (MPS I). Read More

Gastrojejunostomy (GJ) tubes play an essential role in the management of individuals with poor gastric function, chronic vomiting and respiratory problems. Small-bowel intussusception around the GJ tube is uncommon with reported incidence of ~16% (likely to be higher in younger patients and with the use of large bore tubes). Complications associated with GJ tube intussusceptions are typically sub-acute and resolve spontaneously, but in some instances can lead to more severe complications such as bowel obstruction, ischemia and perforation.

Knowing the gestational status of a neonate (premature or full-term) impacts a pediatric radiologist’s ability to generate a reasonable differential diagnosis of neonatal diseases. Though crucial, this information is often unavailable at the time of the babygram interpretation. Conventional methods based on measuring the clavicular-pubic length (CPL) and the transverse diameter of the chest (TDC) from a babygram have been proposed as reliable estimators of a neonate’s gestational age. In this study, we aimed to compare these two conventional methodologies to that of a deep-learning (DL) model in determining a neonate’s gestational status. Read More
