Innovations in pediatric healthcare are advancing diagnostics and treatments. Lung ultrasound is emerging as a transformative tool for neonatal and pediatric respiratory care, offering alternatives to traditional imaging. Automated 3D echocardiography software improves right ventricular assessment accuracy in children. Fetal MRI enhanced by super-resolution techniques boosts congenital heart disease and esophageal atresia diagnosis. Additionally, multimodal neuromonitoring advances in neonates on ECMO improve critical care, and optimized CT imaging aids pediatric abdominal trauma management.
