Predictive value of quantitative contrast-enhanced ultrasound in hepatocellular carcinoma recurrence after ablation

Figure 1 Time-intensity curve of patients in the non-recurrence group. A: Time-intensity curve of ROI in the tumor. The green curve was gentle, and indicated that the change in intensity was less obvious. The Peak was 28.3% and TP was 68.23 s; B: Time-intensity curve of ROI beyond the tumor. The green curve was gentle and similar to the ROI curve in the tumor. The Peak was 29.1% and TP was 62.26 s. ROI: Region of interest.

Figure 2 Time-intensity curve of patients in the recurrence group. A: Time-intensity curve of ROI in the tumor. The green curve was steep, and indicated that the change in intensity was obvious. The Peak was 35.5% and TP was 43.33 s; B: Time-intensity curve of ROI beyond the tumor. The green curve was gentler, compared with the ROI curve in the tumor. The Peak was 33.5% and TP was 57.29 s. ROI: Region of interest.
