These lymph nodes receive drainage from the lower gastrointestinal tract and the pelvic organs. Optimal techniques include imaging after oral administration of adequate amounts of barium suspension and dynamic scanning after intravenous administration of contrast material with an. Dr Daniel J Bell and Dr Mila Dimitrijevic et al.

Diagnosis of lymphadenopathy is facilitated by optimal imaging techniques and a knowledge of the various nodal chains their complex interconnections and preferential pathways of spread. They appear inhomogeneous and are necrotic. As part of the lymphatic system these nodes help drain.

26 June 2015 PLOS ONE Vol. 4L nodes are lower paratracheal nodes that are located to the left of the left tracheal border between a horizontal line drawn tangentially to the upper margin of the aortic arch and a line drawn tangentially to the upper margin of the left pulmonary artery.
