There is a widespread lack of familiarity with the normal appearance of the fetal brain in the early second trimester (12-18 weeks), particularly in MRI. Interpreting these images is challenging because of the continuous fetal motion, small size of structures, and immature appearance of the brain. This educational exhibit aims to increase awareness of the appearance of the fetal brain between 12- and 18-weeks gestation by presenting images of normal fetuses and establishing a correlation with same day ultrasound. All fetuses included in this exhibit were proven to have normal brains on late gestation fetal and/or post-natal brain MRI. After viewing this exhibit the reader will (1) recognize the normal appearance of the brain in the early second trimester, (2) understand the specific developmental trajectories of major structures (ventricles, corpus callosum, etc…), (3) establish a correlation between the sonographic appearance and the fetal MRI.

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
