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 4

A 33-year-old Male had a mixed nodule in the left lobe of the thyroid. (a) Ultrasound examination showed a 13 × 8 mm mixed nodule protruding from the front capsule before LA. (b) Ultrasound examination showed a 16.8 × 9.8 mm ablation lesion one day after LA. (c) CEUS showed no enhancement of the ablation lesion one day after LA. (d) Six months after LA, Ablation lesion had an obvious volume reduction, and no prominent capsule was observed. (e) Nine months after LA, ablation lesion had an obvious volume reduction compared with the six-month results. (f) 12- month after LA, the ablation lesion had disappeared.
