Ultrasound-Guided Fine-Needle Aspiration Biopsy of Thyroid Nodules: Comparison in Efficacy According to Nodule Size

Abstract

US-FNAB of thyroid nodules smaller than 5 mm in maximum diameter was less successful, and the sensitivity was lower than those of nodules larger than 5 mm. We considered, however, that the sampling adequacy and efficacy of US-FNAB of thyroid nodules less than 5 mm in maximum diameter was satisfactory in our series and should be similar in other centers with similar characteristics to ours.
