[Contrast retention in retroperitoneal lymph nodes after lymphography; the effect of lymph node abnormalities, radiotherapy and contrast quantity].
The rate of contrast loss from retroperitoneal lymph nodes after lymphography was studied radiologically over a prolonged period in 302 patients. It varied remarkably, even in normal persons who were not receiving any treatment. Lymph nodes empty more quickly if only a small quantity of contrast has been used. Irradiation accelerates contrast transport, not only in the irradiated, but also in the neighbouring, group of nodes. This effect is dose dependent. There is evidence that pathological lymph nodes empty more quickly than normal ones.
