Liver, Biliary Tract, and Spleen

Hepatic US in children should be focused on hepatic vascularization. Real-time US makes such a study much easier. Five scans are mandatory: a longitudinal scan through the long axis of aorta, a longitudinal scan through the inferior vena cava (IVC), a subcostal oblique scan-through the confluence of the hepatic veins, a subcostal oblique scan through the portal vein bifurcation, and a longitudinal oblique scan through the long axis of the portal trunk.
