Contrast-enhanced ultrasound: Improving the preoperative staging of hepatocellular carcinoma and guiding individual treatment

Figure 2 A 55-year-old woman underwent right hepatic partial resection. A-C: both lesions, displayed in the arterial, portal venous and equilibrium phases, were diagnosed as HCC by CT (white arrow); D-F: the HCC (yellow arrow) displayed wash-in in arterial phase and wash-out in late phases via CEUS; another lesion (white arrow), diagnosed as necrosis by final histopathology, displayed iso-enhancement in the three phases; G: the HCC identified by IOUS; H: the necrosis also falsely diagnosed as HCC by IOUS. HCC: Hepatocellular carcinoma; CT: Computed tomography; CEUS: Contrast-enhanced ultrasound; IOUS: Intraoperative ultrasound.
