Abstract
A radioactive composition for the scintigraphic imaging of the hepatobiliary system is disclosed, the composition comprising a complex of .sup.99m Tc with a [2,6-di(lower)alkyl or 2,4,6-tri(lower)alkyl-acetanilido]-iminodiacetic acid having a total of at least 3 carbon atoms in the alkyl groups, or a salt thereof, in sterile aqueous solution. In a preferred composition the complex contains in addition a tin salt and is prepared directly prior to use by reacting NaTcO.sub.4 with SnCl.sub.2 and the iminodiacetic acid.
