A t-tube cholangiogram is a special x-ray procedure that is done with contrast media (x-ray dye) to visualize the bile ducts after the removal of the gallbladder.
Oral cholecystogram: Abbreviated OCG. An x-ray procedure for diagnosing gallstones. The patient takes iodine-containing tablets by mouth for one night or two nights in a row. The iodine is absorbed from the intestine into the bloodstream, removed from the blood by the liver, and excreted by the liver into the bile. The iodine, together with the bile, is highly concentrated in the gallbladder. Iodine is used in an OCG because it is dense and radioopaque (stops x-rays).
