Detection of the Single-Session Complete Ablation Rate by Contrast-Enhanced Ultrasound during Ultrasound-Guided Laser Ablation for Benign Thyroid Nodules: A Prospective Study

Figure 1

(a) A left lobe nodule near the front capsule; a “hydrodissection technique zone” (arrow) formed in front of the thyroid after liquid injection. (b) A right lobe nodule near the thyroid back capsule; a “hydrodissection technique zone” (arrow) formed at the back of the thyroid after liquid injection. (c) A right lobe nodule nears the carotid; a “hydrodissection technique zone” (arrow) formed outside the thyroid after liquid injection. (d) A right lobe nodule close to the trachea; a “hydrodissection technique zone” (arrow) formed inside the thyroid after liquid injection.
