Fine-needle aspiration biopsy of the thyroid (FNAB) can rule out thyroid cancer, make a diagnosis or select therapy for a thyroid nodule, or drain a thyroid cyst. Thyroid fine-needle aspiration (FNA) bi-opsy is the most reliable, safe, and cost-ef-fective diagnostic tool used in the defini-tive evaluation of thyroid nodules, especially when done under ultrasound (US) guidance, and has a 95–97% accuracy rate [2, 8–10]. Alcohol Ablation Alcohol ablation therapy (also called percutaneous ethanol injection, PEI) is a treatment that can be used to shrink large thyroid cysts and fluid-filled nodules, as well as destroy recurrent thyroid cancer lymph nodes without surgery. Thermal ablation (TA) has been widely used and regarded as a safe and effective method to eliminate or reduce BTNs and recurrent low-risk PTMC.
