Lipiodol: from intrusion until exile from the tumor microenvironment.

Abstract

Lipiodol or ethiodized oil, which is extracted from poppyseed oil, is a transparent straw-colored oil which sinks when combined with water [1]. Lipiodol does not dissolve when combined with aqueous solutions and can be iodinated with I 131 , thus making the compound both imageable and therapeutic. The radiopacity of lipiodol originates from its iodine content.
