Overview
Other Imaging Findings
ERCP
ERCP has been regarded as the gold standard for diagnosis because it allows good visualization of the biliary system and the pancreas. However, MRCP is currently preferred due to its noninvasive nature.[1] Common findings include:[2]
- Multiple segmental strictures
- Biliary dilatation: may be present in ~85% of cases
- Biliary diverticula
- Mural irregularities
- Distortion of the biliary tree due to associated cirrhosis
MRCP

Coronal thick-section MRCP showing a high-grade hilar stricture (straight arrow) with proximal dilatation, multifocal intrahepatic strictures and dilatation and a beaded appearance of the anterior right hepatic duct (curved arrow).

This ERCP image shows several strictures of the anterior right hepatic duct alternating with areas of dilatation, thus producing a beaded appearance (arrows). Adapted from RadioGraphics http://pubs.rsna.org/doi/full/10.1148/radiographics.20.4.g00jl04959. Accessed on Dec 12, 2016.
