Ultrasound of the Liver -Protocol To assess the: Size Texture: Capsular contour (smooth, coarse, lobulated) Parenchymal echogenicity Vascularity Biliary tree Masses or collections OBJECTIVES NORMAL LIVER DISEASED LIVER by U/S. by U/S. The left branch of the portal vein has a longer travel to the left before dividing into medial and lateral segmental branches. Right portal vein divides early into anterior and posterior segmental branches. Hepatic Artery The common hepatic artery is one of the final branches of the celiac artery. It supplies oxygen-rich blood to the liver. The artery then passes upward toward the porta hepatis, The proper hepatic artery enters the porta hepatis where it splits into the left and right hepatic arteries that supply the liver. Three main hepatic veins drain the liver and lie between major hepatic segments. The middle hepatic vein lies between the right and left lobes. The left hepatic vein lies between the medial and lateral segments of the left lobe. The right hepatic vein lies between the anterior and posterior segment of the right lobe. The intersegmental positions of these veins necessitate division of the hepatic parenchyma to one side of the anatomic division when doing hepatic resectionin order to reduce blood loss. Preparation Ideally, fast the patient for 6hours to reduce bowel gas and prevent gall bladder contraction. Portal vein Diameter:
