Read more Background Pulmonary and mediastinal diseases in infants and children encompass a diverse group of congenital and acquired disorders. Clinical presentations are often nonspecific, causing delayed or missed diagnoses. Chest radiography, though commonly used initially, often necessitates further evaluation with computed tomography (CT), which poses risks due to ionizing radiation, especially with repeated imaging [1].Magnetic resonance imaging (MRI) offers a radiation-free alternative to CT, providing excellent soft-tissue contrast and functional insights. Historically limited by challenges such as low lung proton density and...
Read more Findings and procedure details 1. Procedure details and patient preparation (Figure 1) [fig 1] For lung MRI, the patient should be positioned supine. While a body coil may be used, a local receive coil array optimized for thoracic imaging significantly improves signal-to-noise ratio (SNR). Thoracic MRI coils typically include a flexible anterior and an embedded posterior part [4].Children over 5 years can often perform coached breathing maneuvers during the scan. For younger children, moderate sedation or general anesthesia is used with free-breathing techniques. Infants are commonly scanned...
Read more Conclusion Despite its limitations, lung MRI holds great potential as a radiation-free alternative to CT, offering superior soft-tissue contrast and functional imaging capabilities. Continued advancements in MRI technology may further enhance its role in the comprehensive assessment of pediatric thoracic diseases.
