Focal liver lesions in cirrhosis: Role of contrast-enhanced ultrasonography

Figure 8 Focal nodular hyperplasia. A: Contrast-enhanced ultrasound examination in the early arterial phase (16 s after the i.v. injection of contrast agent) shows a spoke-wheel appearance (left, arrow); B: Four seconds later, still in the arterial phase the lesion is homogeneously and strongly enhancing (left, arrow); C: In the late phase (180 s after the injection) the lesion is still slightly hyperechoic to the adjacent liver parenchyma.
