''' Intravenous cholangiography''' is a form of [[cholangiography]] that was introduced in 1954.<ref name="Baert2008">{{cite book|author=Albert L.

==Procedure==

To do an IVC, an iodine-containing dye ([[meglumine]] [[ioglycamate]]) is injected intravenously into the blood. The liver then removes the dye from the blood and excretes it into the bile. The iodine is sufficiently concentrated as it is secreted into the bile that it does not need to be further concentrated by the [[gallbladder]] to outline the bile ducts and any gallstones that may be there. The gallbladder is not always seen on an IVC, as the iodine-containing bile may bypass the gallbladder entirely and empty directly into the [[small intestine]].

==Indications==

TheCurrently, IVC is not used as muchcommonly today as it wasperformed. Its use always was always limited, because it did not work when there was more than a minimal amount of [[jaundice]], and many of the conditions it was used to detect also caused substantial jaundice. The IVC has been largely replaced by other diagnostic procedures—byprocedures ERCPincluding ([[endoscopic retrograde cholangiopancreatography|endoscopic retrograde cholangiopancreatography (ERCP)]]), [[endoscopic ultrasound]] and, increasingly, by [[MRIMagnetic resonance cholangiopancreatography|magnetic resonance cholangiopancreatography (MRCP)]] cholangiography, none of which are affected by jaundice. It is sometimes used when ERCP is unsuccessful.<ref name="KuntzKuntz2008">{{cite book|author1=Erwin Kuntz|author2=Hans-Dieter Kuntz|title=Hepatology: textbook and atlas : history, morphology, biochemistry, diagnostics, clinic, therapy|url=https://books.google.com/books?id=oL6d9KuVqLQC&pg=PA191|access-date=3 July 2011|year=2008|publisher=Springer|isbn=978-3-540-76838-8|pages=191–}}</ref>
