A percutaneous transhepatic cholangiogram (PCTA) is an x-ray of the bile ducts in and around the liver.
The fluoroscopy (live x-ray) machine is used to guide a needle into the bile ducts, then x-ray contrast medium is injected into the bile ducts. The medium can be seen flowing through the ducts if there are no blockages. Blockages can be identified for further treatment.
PCTA is a needle-based procedure performed in our freestanding facility in Dayton, Ohio. The procedure will take about an hour and no overnight stay is required.
