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

Figure 2 Hepatocellular carcinoma. A: Contrast-enhanced ultrasound examination in the arterial phase (30 s after the i.v. injection of contrast agent) shows a 3 cm sized hypoechoic nodule, showing a marked contrast enhancement (right, arrow); B: In the portal phase (70 s after the injection) the lesion is still hyper-enhancing in comparison to the adjacent liver parenchyma (arrows); C: Only waiting for the extended portal phase (i.e. 122 s after the injection) the lesion shows a mild and late wash-out and appears moderately hypoechoic (arrows).
