Lymphography is a medical imaging technique in which an interventional radiologist injects radiocontrast agent, and then an X-ray picture is taken to visualise structures of the lymphatic system, including lymph nodes, lymph ducts, lymphatic tissues, lymph capillaries and lymph vessels
How is a lymphangiogram done?
During lymphangiography, the physician will place small needles into lymph nodes in the groin area. A small amount of a contrast agent (a safe, injectable dye) will be injected into the needles and tracked by, X-ray or fluoroscopy as it travels upward through the lymphatic system.
