Tumor vascularity of a transplantable N-methyl-N-nitrosoguanidine induced adenocarcinoma of the colon in the liver was investigated by repeated hepatic arteriography and portography. The arterial vascularity was influenced by tumor size; a transient increase in vascularization was observed when tumor size increased. Portography revealed portal vessels concentrated to the peripheral parts but some portal vessels were also observed leading to the central part of the adenocarcinomas. The tumor volume of solitary adenocarcinoma of the liver could be estimate measurements of the largest (a) and smallest (b) diameters on the angiogram according to the formula V = a .times. b2/2.
