Comparison of Thyroid Fine-Needle Aspiration and Core Needle Biopsy [PDF]

American Journal of Clinical Pathology, 2007
We compared the adequacy and accuracy of fineneedle aspiration (FNA) with core needle aspiration in a total of 377 patients who underwent both tests. The adequacy rate for core needle biopsy (82.2%) was significantly higher than that of FNA (70.3%; P < .001), but the combined adequacy was significantly higher than that for either test alone (88.9%; P <
