Contrast-enhanced ultrasonography for the evaluation of liver fibrosis after biliary obstruction

Figure 1 Time-intensity curve from contrast enhancement ultrasonography of the liver of a rabbit. The contrast enhancement ultrasonography (CEUS) was performed with a high frequency linear transducer and the time-intensity curve was automatically presented as an absolute time to echo mean (dB) curve with a curve fitting method.

Figure 2 Peak signal intensity and liver fibrosis grade associations. The peak signal intensity measured on the last day showed significant association with liver fibrosis grades with an OR = 1.392 (95%CI: 1.114-1.741, P = 0.004).
