Sonazoid-contrast-enhanced ultrasound for the histological diagnosis of hepatocellular carcinoma

Figure 2 Ultrasound figures of a case of poorly differentiated hepatocellular carcinoma. The figure presents the case of a 50-year-old male patient without chronic hepatitis B, in whom a liver mass was revealed as poorly differentiated hepatocellular carcinoma with vascular invasion, and a Ki-67 expression of about 50%. A: An ultrasound image showing a mass approximately 3.1 cm in diameter located in the right lobe of the liver; B: Ultrasound image showed abundant short linear blood flow signals in the lesion; C-F: Sonazoid-contrast-enhanced ultrasonography images showing a rapid enhancement of the mass in arterial phase and early washout in the following three phases.
