Lymphogram
（重定向自Lymphography）
Lymphography is a medical imaging technique in which a radiocontrast agent is injected, and then an X-ray picture is taken to visualize structures of the lymphatic system, including lymph nodes, lymph ducts, lymphatic tissues, lymph capillaries and lymph vessels. Lymphangiography is the same procedure, used only to visualize the lymph vessels. The X-ray film or image of the vessels and nodes is called a lymphogram or a lymphangiogram.
