Enhancement Effect of Microbubble-Enhanced Ultrasound in Microwave Ablation in Rabbit VX2 Liver Tumors

Figure 2

Contrast-enhanced ultrasound images of the tumors from three treatment groups before and after treatment. All liver tumors presented a nonuniform high enhancement model with weak enhancement at the centre (a, c, e) before treatment. After MEUS cavitation, tumor perfusion was decreased and the enlarged unenhanced perfusion defects appeared (b). After MWA ablation, a round-shaped enhancement defect lesion appeared (arrow in (d)). The liver tumor treated by using MEUS + MWA combination showed a much more regular and lower enhancement ablation zone (arrow in (f)).
