Magnetic Resonance Lymphangiography in Children: What the Radiologist Needs to Know.

Magnetic resonance lymphangiography (MRL) has revolutionized the evaluation of lymphatic system disorders in pediatric patients, offering unparalleled details without the risks of ionizing radiation. This imaging modality is pivotal for diagnosing congenital lymphatic anomalies, chylothorax, lymphedema, and vascular malformations, which require precise characterization for optimal management. Pediatric radiologists must understand MRL's technical nuances, including contrast protocols, imaging sequences, and postprocessing techniques, as well as its role in guiding therapeutic interventions. This article provides a comprehensive overview of MRL in children, highlighting its indications, interpretative challenges, and the integration of findings into multidisciplinary care for this complex patient population.
