Dynamic contrast-enhanced magnetic resonance lymphangiography: a simple algorithm for image interpretation.

Dynamic contrast-enhanced magnetic resonance lymphangiography is a high-resolution imaging technique that has emerged as the preferred method for evaluating lymphatic anatomy and flow dynamics due to its precise anatomical detail. The lymphatic system has a complex anatomical distribution, and variability is common among individuals with cardiac abnormalities, particularly congenital heart disease. Lymphatic imaging has recently been revolutionized by the introduction of MR lymphangiography. However, challenges in interpreting these images persist due to limited availability of this modality, and the expertise required for its performance and interpretation, especially in pediatric patients. We aim to outline a simple algorithm employed in our practice for interpreting MR lymphangiography images for pediatric radiologists.
