Iotasul, a water-soluble contrast agent for direct and indirect lymphography. Results of preclinical investigations.

Iotasul, a non-ionic dimeric water-soluble contrast agent with outstanding physico-chemical properties is well suited for direct as well as indirect lymphography, as demonstrated in experimental animals. The contrast medium is eliminated practically completely within 24 hours by the renal route. The tolerance of this agent is far better than that of oily contrast media.
