Introduction Ultrasound-guided thyroid fine needle aspiration and biopsy (FNAB) has become the test of choice for evaluation of thyroid nodules. It combines ease of access and a high sensitivity and specificity to offer reliable results to aid

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

therapeutic resources [ 5 , 6 ]. Thyroid fine-needle aspiration (FNA) cytology has proven to be the most accurate, safe, efficient, and cost-effective screening and diagnostic tool for the preoperative distinction of benign from malignant nodules [ 3 , 4 ]. It

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 (FNA) cytology [ 1 - 5 ]. Robust evidence demonstrates that the risk of

thyroid nodules are benign, and 5–15% of them are thyroid malignancies. Fine-needle aspiration biopsy (FNAB) is a reliable, minimally invasive diagnostic method with high sensitivity and specificity in the evaluation of thyroid nodules [ 2 , 4 - 7

hilum, rounded shape, hyperechoic punctuations, cystic formation, peripheral vascularization, and microcalcifications [ 8 ]. Suspicious LNs are confirmed through fine needle aspiration (FNA) cytology guided by ultrasound (US). Nevertheless, inadequate

Introduction The Bethesda System for Reporting Thyroid Cytopathology (BSRTC) recommends repeat fine-needle aspiration (RFNA) for thyroid nodules initially diagnosed as atypia/follicular lesion of undetermined significance (AUS/FLUS) [ 1 , 2

Dear Editor, Recently, Russ et al. [ 1 ] endorsed active surveillance for low-risk papillary microcarcinoma of the thyroid (PMT). It is also reasonable to imagine that, if immediate treatment is not necessary, fine-needle aspiration (FNA) of

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
