Simultaneous Fine-Needle Aspiration and Core Biopsy of Thyroid Nodules and Other Superficial Head and Neck Masses Using Sonographic Guidance

Abstract
OBJECTIVE. The objective of our study was to conceive of and to evaluate a simple system for simultaneous fine-needle aspiration (FNA) and core biopsy of thyroid nodules when FNA alone has failed to yield tissue adequate for diagnosis. CONCLUSION. The use of a modified coaxial guiding needle and biopsy gun is a simple, safe, and effective method for obtaining tissue from thyroid nodules and is applicable to sampling other superficial masses as well.
