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

To assess the equivalence of MRI without Gd-based contrast and MRI with contrast in the evaluation of synovitis in pediatric patients with juvenile idiopathic arthritis (JIA). Contrast-enhanced imaging has been the gold-standard for MR evaluation of synovitis in patients with JIA (JAMRIS system). Conventional 2D MRI sequences did not allow reliable differentiation between synovium vs joint fluid. With higher field-strength magnets (1.5T or 3T), and high-resolution 3D sequences, the synovium may be differentiated from joint fluid on noncontrast MRI. Read More

Children with suspected developmental dysplasia of the hip (DDH) often undergo both anteroposterior (AP) and frog-leg lateral (FL) radiographs of the hips to derive their associated acetabular indices (AI) in gauging the maturity and development of their hips. Unfortunately, when the AP view is suboptimally positioned, repeat imaging is often necessary, resulting in additional radiation exposure. This study aims to determine whether FL radiographs are equivalent to AP radiographs for measuring AI in children being evaluated for suspected DDH. Read More
