CT cholangiography can be performed using iodipamide
meglumine (Cholografin, Bracco).
Poly(D,L-lactide) microspheres  and iodipamide
ethyl ester (IDE) particles  were previously reported to aggregate inside the body after intravenous injection.
Another method for visualizing the biliary tract is intravenous cholangiography (IVC), introduced in 1953. This procedure used sodium or meglumine iodipamide
as the contrast media.
