Fine needle aspiration biopsy (FNAB) and cytology constitute the gold standard for the diagnostics. Ultrasonography provides an irreplaceable tool for assessing the nature of thyroid nodules improving the detection of malignancy and reducing unnecessary biopsies. recently a few recommendations and sonographic classifications have emerged.
