Comparative MRI Analysis of Morphologic Patterns of Bile Duct Disease in IgG4-Related Systemic Disease Versus Primary Sclerosing Cholangitis

Abstract

The presence of continuous as opposed to skip disease in the bile ducts, gallbladder involvement, and single-wall common bile duct thickness greater than 2.5 mm supports a diagnosis of ISD over PSC. ISD and PSC could not be differentiated on the basis of location and length of common bile duct stricture.
