Figure 1. Arterial phase (A, C) and portal phase (B, D) seen in MSCT and CEUS, in the same patient with multifocal hepatocarcinoma. CEUS (C, D) appears in a double image: B mode on the left and contrast enhancement on the right. Both modalities allow a good evaluation of the hypervascularization of the lesions in arterial phase (arrows) and the wash-out in the portal phase. MSCT allows the same scan in the arterial phase (A) to show 4 nodules. CEUS, in its windows in the same phase (C) shows only 2 nodules. CEUS allows an extremely rapid scan of the arterial phase (C) with enhancement of lesions after 11 s since the administration of MdC. MSCT: multislice computed thomography; CEUS: contrast enhanced ultrasound
