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

==What is an Intravenous Cholangiography?==

==Overview==

The intravenous cholangiogram or IVC is a radiologic (x-ray) procedure that is used primarily to look at the larger [[bile duct]]s within the liver and the bile ducts outside the liver. The procedure can be used to locate [[gallstone]]s within these bile ducts. IVC also can be used to identify other causes of obstruction to the flow of bile, for example, narrowings (strictures) of the bile ducts and cancers that may impair the normal flow of bile.

==Procedure==

==How is an Intravenous Cholangiography done?==

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]].

==Risks==

==What are the risks regarding Intravenous Cholangiography?==

Occasional serious allergic reactions can occur to any iodine-containing dye. These reactions can usually be treated and rarely result in death.

==Indications==

==When is the intravenous cholangiogram useful?==

TheCurrently, IVC is not used as muchcommonly today as it wasperformed. Its use was always was 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 --including by ERCP ([[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=httphttps://books.google.com/books?id=oL6d9KuVqLQC&pg=PA191|accessdateaccess-date=3 July 2011|year=2008|publisher=Springer|isbn=978-3-540-76838-8|pages=191–}}</ref>
