Lymphangiographic appearances in the rat.

Standard texts on the anatomy of the rat deal very perfunctorily with the appearances of the lymphatic system (1, 2) and no description of the normal radiological findings could be located in the literature. In a previous communication (3) the method of performing this examination in rats was described. The present paper is based upon the results of 24 lymphangiographies and is presented as there are certain fundamental differences from those occurring in humans. Any investigator using this technique must therefore be aware of these aspects.
