Lymphography

To perform lymphography, the contrast agent is injected directly into the lumen of the lymphatic vessel. Currently, the clinic mainly performs lymphography of the lower extremities, pelvis, and retroperitoneal space. The contrast agent - a liquid oil emulsion of an iodine compound - is injected into the vessel at a rate of 0.25-0.5 ml/min. Radiographs of the lymphatic vessels are taken after 15-20 minutes, and radiographs of the lymph nodes - after 24 hours.

Indications for lymphography are relatively narrow. It is used in systemic and tumor diseases to clarify the localization, degree and nature of damage to the lymph nodes. In particular, such a need may arise when planning radiation therapy for cancer patients. However, due to the development of computed tomography, which allows obtaining a clear image of the lymph nodes, the use of lymphography in oncology clinics is currently limited.
