Hepatic steatosis. Perhaps the most objective, and therefore the most important, sign of hepatic steatosis is the circumscribed focal hypoechoic areas in the liver hilum examined in a left posterior oblique position. (a) B-mode ultrasound demonstrates a focal liver lesion in between callipers (+). (b) Colour Doppler imaging indicates a centrally located vessel of undetermined origin. (c) Contrast-enhanced ultrasound shows the typical enhancement pattern. Typically a centrally located arterial vessel can be displayed [(33;39)] in the arterial phase (arrow) and (d) a portal vein branch in the portal venous phase (arrow) and homogenous enhancement in the late phase [(39)].
