'''Percutaneous transhepatic cholangiography''' ('''PTHC''' or '''PTC''') is a diagnostic test used to visualize the [[anatomy]] of the [[biliary tract]]. A [[contrast medium]] is injected into a bile duct in the [[liver]], after which [[X-ray]]s are taken. It has various purposes, such as the visualisation of the biliary tree in cases where [[endoscopic retrograde cholangiopancreatography]] (ERCP) has been unsuccesful. Initially reported in 1937, the procedure became popular after a 1952 report in the English-language literature.<ref name="pmid11429953">{{cite journal |author=ParkCarter SJRF, HanSaypol JK,GM Kim|title=Transabdominal TK, Choi BIcholangiography |titlejournal=Three-dimensionalJournal spiralof CTthe cholangiographyAmerican withMedical minimumAssociation intensity|volume=148 projection|issue=4 in|pages=253–5 patients|year=1952 with|pmid=14888454 suspected|doi=}}</ref><ref>{{cite obstructivejournal biliary|author=Atkinson disease:M, comparisonHappey withMG, percutaneousSmiddy FG |title=Percutaneous transhepatic cholangiography |journal=Abdominal imagingGut |volume=261 |issue=3 |pages=281–6357–65 |year=20011960 |pmid=1142995313684978 |doi=}}</ref> AIf contrastthe mediumbiliary system is injectedobstructed, intoPTC amay be used to drain bile ductuntil ina permanent solution for the obstruction is performed (e.g. surgery).
