Imaging Modalities


  • Ultrasound is the starting point for imaging the bile ducts and gallbladder.
  • ERCP and PTHC allow for direct imaging of the biliary ducts. MRCP is a non-invasive alternative for imaging the biliary system.
  • If involvement beyound the biliary system is suspected, CT may be performed.
  • A more thorough discussion of these techniques may be found under the pancreatic procedures page.
