title: Distribution of 169Yb microspheres and colloidal 198Au following injection into the rectal submucosa in dogs.
abstract: A comparison between two tracers, the one colloidal suspension of 198Au, the other 169Yb-labelled microspheres of 8 to 10 micron has been made concerning lymphatic and hematogenous spread from the submucosa in the rectum in dogs. Both tracers have, in principal, the same distribution. It was therefore considered that a colloidal suspension of 198Au is a useful tracer for functional anatomic investigations of lymph drainage.
