Ultrasound-Guided Fine-Needle Aspiration Versus Fine-Needle Capillary Sampling Biopsy of Thyroid Nodules

摘要

Both fine-needle aspiration (FNA) and fine-needle capillary (FNC) sampling of palpable thyroid nodules have been advocated. The appropriate technique for biopsy of nonpalpable nodules now sampled under ultrasound guidance has not been assessed. The objective of this study was to determine cytologic adequacy rates of ultrasound-guided FNA and FNC sampling.
