Demonstration of dilated biliary ducts by total-body opacification. Differentiation of surgical from nonsurgical jaundice.

Differentiation of surgical from medical jaundice remains a difficult clinical problem. Dilated biliary ducts can be demonstrated by total-body opacification (TBO) and their typical appearance is presented. This suggests that TBO may represent a noninvasive adjunct in distinguishing surgical from medical jaundice.
