Superb Microvascular Imaging Compared with Contrast-Enhanced Ultrasound for Assessing Laser Ablation Treatment of Benign Thyroid Nodules

Figure 2

A 32-year-old man with a completely ablated nodule at the left lobe of the thyroid. (a) The original size of the nodule was 21 mm × 11 mm × 13 mm. (b) Intraoperative 2D-ultrasound monitoring showed that the nodule was completely covered by a patchy hyperecho gasification area. (c) Postoperative CEUS showed that no contrast agent filled the ablated region, which was not enhanced. Its range was larger than the original size of the nodule. (d) Color SMI showed that there was no microvascular perfusion within the ablated lesion. (e) Monochrome SMI also showed no microvascular perfusion within the ablation zone.
