Radiofrequency Ablation Compared to Surgery for the Treatment of Benign Thyroid Nodules
Figure 2
Longitudinal B-mode and power Doppler US images, obtained before (a-b) and after RFA (c-d), show the effects of the procedure at 1 month. The danger triangle, which remains undertreated, is clearly visible on the medial side of the nodule (c-d). Apart from the overall reduction in size, the treated area of the nodule appears hypoechoic and avascular (c-d).
