Dynamic contrast-enhanced MR lymphangiography (DCEMRL) with intranodal injection has emerged as a useful tool in evaluating lymphatic disorders. We share our institutional experience with DCEMRL in infants through a detailed discussion of technique and series of case presentations. Techniques for nodal access and imaging infants with DCEMRL are explained through text and step-by-step illustrations. MR lymphangiography images of infants between 22 days and 8 weeks of age are presented with multi-modality correlation, including patients with congenital chylous ascites, non-immune fetal hydrops, and postsurgical chylothorax. Each case discussion includes a review of relevant lymphatic anatomy, explanation of the disease process, and key teaching points regarding DCEMRL in infants.
