Ultrasound-Guided Percutaneous Microwave Ablation for Solid Benign Thyroid Nodules: Comparison of MWA versus Control Group

Figure 2

Comparison of the mean volume reduction rate (VRR) of the nodules at baseline (time of microwave ablation) and at follow-up after treatment. The VRR at 3-, 6-, 9-, and 12-month follow-ups was 55.98%, 69.31%, 76.65%, and 84.67% in the MWA group, respectively, while the VRR at 3-, 6-, 9-, and 12-month follow-up in the control group was 2.07%, −13.03%, −16.67%, and −24.53%, respectively.
