Presentation transcript:

Conventional and contrast enhanced images of a lesion in the left lobe of the liver. (A) Conventional US scan of the right lobe shows marked steatosis of the liver and an uncharacteristic hypoechoic small focal liver lesion (1.2 cm in diameter). (B–G) Contrast-enhanced US with a bolus of 2.4 mL SonoVue demonstrates typical enhancement characteristics at split screen (left side: contrast-enhanced US scans; right side: conventional US information). (B) Very early arterial phase with detection of a centrally located artery only. (C and D) Early arterial phase with spoke-wheel sign. (E and F) Late arterial and portal venous phases with intense globular enhancement. (G) Late phase shows the FNH as slightly hyperechoic. (Used with permission from Rettenbacher T.
