Surgeon-performed ultrasound-guided thyroid fine-needle aspiration biopsy: Evaluation of 470 biopsies

Background Ultrasound-guided FNAB of thyroid nodules is considered to be the most reliable and feasible test for the diagnosis of thyroid malignancy. We aimed specifically to assess the accuracy of surgeon-performed ultrasound (SPUG)-guided FNAB on a per-nodule basis, with a subanalysis of nodule size and on-site evaluation.
