Recent developments in lymphatic imaging have improved our understanding of the central lymphatic disorders and their management. Magnetic resonance (MR) lymphangiography has been increasingly used as an initial imaging modality for the diagnosis of lymphatic disorders, guiding treatment decisions and evaluating outcomes after treatment in the pediatric population.
MR lymphangiography has several advantages over conventional fluoroscopic intranodal lymphangiography with oil contrast. It has the ability to obtain high-quality cross-sectional anatomical information and real-time dynamic imaging while avoiding exposure to ionizing radiation and other risks of oil contrast in patients with a right-to-left cardiac shunt, severe pulmonary insufficiency, and thyroid dysfunction.
This chapter reviews up-to-date imaging techniques and clinical applications of MR lymphangiography for assessing the central conducting lymphatic ducts and their abnormalities in the pediatric population.
