Figure 2. Arterial phase (A, C) and portal phase (B, D) seen in MSCT and CEUS in the same patient with hepatocarcinoma. MSCT (A, B) allows a good documentation of the nodular lesion (arrows) slightly hypervascular in the arterial phase with wash-out in the portal phase. In CEUS the lesion, not detected in B mode, is isovascular in the arterial phase (C); in the portal phase (D) is slightly hypovascular (black arrow head). MSCT: multislice computed thomography; CEUS: contrast enhanced ultrasound
