Evaluation of sorafenib for hepatocellular carcinoma by contrast-enhanced ultrasonography: A pilot study

Figure 3 Comparisons between the mean time and therapeutic effects according to modified response evaluation criteria in solid tumors evaluated by dynamic computed tomography. A: Median difference in the mean time (MT) was 1.13 s, 2 wk after the treatment in the 8 patients who showed stable disease (SD)/partial response (PR) on dynamic computed tomography (CT). Median difference in the MT was -0.39 s, 2 wk after the treatment in the 5 patients who showed progressive disease (PD); B: Median difference in the MT was 1.015 s, 4 wk after the treatment, in the 8 patients who showed SD/PR on dynamic CT. Median difference in the MT was -0.95 s 4 wk after the treatment in the 5 patients who showed PD. Differences in the median MT between SD/PR and PD groups were significant 2 and 4 wk after the treatment with P = 0.019 and P = 0.028, respectively.
