- X-rays: Often the first-line imaging modality, especially for evaluating respiratory distress, congenital heart disease, and skeletal anomalies. - Ultrasound: Preferred for its safety and utility in assessing brain structures, abdominal organs, and guiding procedures like intravenous catheter placements. - MRI: Provides detailed images of soft tissues and is invaluable in evaluating brain injuries, congenital malformations, and spinal cord anomalies. - CT Scans: Used less frequently due to radiation concerns but can be essential for detailed cross-sectional images of the brain and other organs.
