What is an ultrasound-guided fine needle aspiration biopsy (FNAB)?
Feb 14, 2022
FNAB is a method of puncturing the thyroid, lymph nodes and other parts through the skin under the guidance of direct vision ultrasound, obtaining tissue strips or cell components in the lesion area, and sending them for pathological examination. FNAB is currently the only non-surgical method that can identify benign and malignant thyroid nodules. This method is simple and safe, and avoids unnecessary surgery and postoperative risks. It is an internationally recognized gold standard for the identification of benign and malignant thyroid nodules.
