To perform lymphography contrast substance is poured directly into the lumen of the lymphatic vessel. In the clinic, currently conduct mainly lymphography of the lower extremities, pelvis and retroperitoneal space. Contrast substance - a liquid oil emulsion of iodide compound - is introduced into the vessel at a rate of 0.25-0.5 ml / min. Radiographs of lymphatic vessels are made after 15-20 minutes, and radiographs of lymph nodes - after 24 hours.
Indications for lymphography are relatively narrow. It is used for systemic and neoplastic diseases to clarify the localization, extent and nature of lesions of lymph nodes. In particular, such a need may arise in the planning of radiation therapy in cancer patients. However, thanks to the development of computed tomography, which makes it possible to obtain a clear image of the lymph nodes, at present, the use of lymphography in the oncology clinic is limited.
