Introduction For more than three decades, the cornerstones in the clinical management of patients with thyroid nodules have been ultrasound (US) and fine-needle aspiration cytology (FNA) ( 1 , 2 , 3 ). Robust evidence demonstrates that the

Introduction Fine needle aspiration (FNA) is a rapid, cost-effective, and safe test, which is widely used for the diagnosis of thyroid nodules [ 1 ]. The positive predictive value of a malignant FNA cytology (FNAC) result is 97-99% according

Introduction/Background Fine-needle aspiration (FNA) has high sensitivity and specificity in distinguishing benign from malignant thyroid lesions [ 1 ]. However, in 2–16% of cases cytology is not diagnostic [ 2 ], i.e., the material is

-risk PMT, I believe that FNA should precede this decision. At our institution, nodules with highly suspicious features on ultrasonography (US) are always submitted to FNA (irrespective of size) and the latter is repeated when cytology is commenced [ 3 , 4
