Echoes of change: lung ultrasound revolutionizing neonatal and pediatric respiratory care.

Lung ultrasound has emerged as a transformative imaging modality in neonatal and pediatric pulmonary care, offering a radiation-free, bedside, and versatile tool that complements traditional chest radiography. Despite its recognized value in the detection, monitoring, and management of various conditions in neonatal and pediatric intensive care units, the routine application of lung ultrasound for monitoring pneumonia remains underutilized by radiologists. In recent years, lung ultrasound has demonstrated its effectiveness in monitoring disease progression without the need for repeated chest computed tomography scans, particularly in cases of complicated pneumonia. This essay reviews the fundamental principles, key sonographic patterns, and essential applications of lung ultrasound in neonatal and pediatric intensive care units. Case-based experiences are shared to illustrate how lung ultrasound is shaping clinical decision-making and redefining best practices in pulmonary care by minimizing invasive procedures and reducing radiation exposure.
