This allows physicians to see the anatomy of the lymphatic system, as well as the direction and speed of lymphatic flow.

In patients who will need a lymphatic interventional procedure, the physician will typically access the duct using a thin needle inserted through the abdomen. Less frequently, the physician may access the thoracic duct through a vein by catheterizing the duct where it empties into the systemic veins at the top of the chest.
