Figure 3. Arterial phase (A, C) and portal phase (B, D) seen in MSCT and CEUS in the same patient with hepatocarcinoma. In CEUS the nodule (arrows) is slightly hypervascular in the arterial phase (A) with wash out in the portal phase (B). The enhancement is disomogeneous becaus of the presence of an avascular area in the cranial portion of the lesion. In MSCT the lesion is isovascluar in the arterial phase (C). In the portal phase (D) it is hypovascular (black arrow head). MSCT: multislice computed thomography; CEUS: contrast enhanced ultrasound
