The Diagnostic Accuracy of Ultrasound-Guided Fine-Needle Aspiration Biopsy for Thyroid Nodules Three Centimeters or Larger in Size

摘要

Background and Purpose: Whether under ultrasonography (US) guidance or not, fine-needle aspiration biopsy (FNAB) has some limitations, particularly in larger nodules. In this study, we aimed to evaluate the diagnostic value of US-guided fine-needle aspiration biopsy (US-FNAB) in thyroid nodules equal to or larger than 3 cm.
