[Comparison of Ablation Lesions of Porcine Thyroid in Vivo Ablated with Laser].

To explore the ablation effect of porcine thyroid in vivo ablated with 3 W/1800 J ND:YAG laser, ultrasound examination and contrast-ultrasound were done to observe scope of ablation lesion. The experimental results showed that the ablation effect of porcine thyroid in vivo ablated with 3 W/1 800 J ND:YAG laser is definite, and ideal ablation lesion can be formed.
