EXPERIMENTAL OPACIFICATION OF MEDIASTINAL LYMPH NODES BY INTRAPERITONEAL INJECTION OF AN IODINATED FATTY EMULSION

Abstract


Absorption and lymphatic drainage of several lipiodol
emulsions injected intraperitoneally have been
studied in the rabbit and rat. Good opacification
of the lymphatic channels and mediastinal lymph
nodes is obtained in several hours with fine emulsions
and in several days with coarse emulsions.
The tolerance is related to dose, and the peritoneal
reaction was moderate with the low doses, similar
to that caused by the administration of physiologic
saline alone. Computerized tomography in detecting
low contrasts attained with small doses could
render this method of indirect lymphography
possible in man.
