Figure 2.

Effect of liver-specific microbubbles on the visualisation of a hepatocellular carcinoma complicating chronic hepatitis B infection. Top figure shows the liver is heterogeneous with an ill defined lesion (arrow). Bottom figure shows the presence of liver-specific microbubbles (Levovist) administered 5 minutes earlier. A defect is clearly seen in the central right lobe of the liver, with several additional defects thought to represent additional satellite foci of hepatocellular carcinoma
