Comparison of diagnostic values of thyroid aspiration samples using liquid-based preparation and conventional smear: one-year experience in a single institution

Papillary thyroid carcinoma ( PTC ) is the most common thyroid malignancy. Fine‐needle aspiration ( FNA ) is the most useful tool in the diagnosis of thyroid nodules. Liquid‐based preparation ( LBP ) in FNA of thyroid nodules is now widely used and is replacing the conventional smear ( CS ). We compared the diagnostic value of the LBP method with that of CS in thyroid lesions. A total of 1767 CS FNA samples and 2523 LBP FNA samples were included...
