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

Table 1

Comparison of tumor volumes (cm³) before treatment and volumes (cm³) of unenhanced perfusion defects after treatment in each group.

Group	Tumor volume before treatment	Volumes of unenhanced perfusion defects after treatment
Control	1.68 ± 1.04	—
MEUS	1.80 ± 1.03	0.93 ± 0.43
MWA	1.73 ± 1.06	1.78 ± 0.31
MEUS + MWA	1.79 ± 1.05	1.84 ± 0.20

Control = blank control; MEUS = microbubble-enhanced ultrasound; MWA = microwave ablation. Significantly different from the value of MWA or MEUS + MWA combination treatment.
