Ultrasonographic Identification of Dilated Intrahepatic Bile Ducts and their Differentiation from Portal Venous Structures

  • Chapter
Ultrasound in Medicine

Abstract

Ultrasonographic evaluation of hepatic parenchyma has improved remarkably since the introduction of gray scale equipment. Bistable recordings are capable of outlining the organ and showing gross parenchymal abnormalities. Much information regarding the internal architecture of the liver, however, is lost on bistable sonograms. Gray scale technique has revealed that normal hepatic parenchyma is fairly uniform in its echo pattern. Hepatic parenchymal echoes are stronger than those emanating from normal renal tissue, but are weaker than echoes reflected from pancreatic tissue.
