Hepatocellular carcinoma treated with transarterial chemoembolization: Evaluation with parametric contrast-enhanced ultrasonography

Figure 2 Box and whisker plots showing the statistically significant changes observed after transarterial chemoembolization in peak intensity and area under the curve during wash-in, while changes in time to peak were not statistically significant (the upper and lower end of each box corresponds to the 1st and 3rd quartile, respectively, and the horizontal line inside the box corresponds to the median value). PI: peak intensity; AUC-WI: area under the curve during wash-in; a.u: Arbitrary units; TACE: Transarterial chemoembolization.
