- In CT cholangiography, the obstruction of the common bile duct diminishes the flow of contrast agent. Contrast agents used for imaging studies can be complications with an allergic reaction or kidney damage.
- In contrast-enhanced CT, findings include target sign, rim sign, crescent sign, calcification, and biliary dilatation.[1]
