Figure 3 The time-intensity curve of quantitative analysis after contrast-enhanced ultrasonography of the patient with primary hepatic angiosarcoma. A: Regions of interest of the lesion (orange circle) and surrounding hepatic parenchyma (blue circle) were placed manually; B: The time-intensity curve showed that the contrast agent rapidly washed-in within the lesion and rapidly washed-out.
