Objective: Thyroid nodules are one of the most common pathologies among the general population, but there are still some challenges regarding to their treatment and follow up. The aim of this study was to determine the role of Ultrasound guided Fine Needle Aspiration Biopsy (US-guided FNAB) in the evaluation of patients with thyroid nodules.Methods: The 472 patients whose thyroid nodules have been detected was performed US-guided FNAB. The specimens were evaluated and classified as such: unsatisfactory material for proper cytological diagnosis, benign, suspected of malignancy and malignant. 146 of the patients were operated.Results: The accuracy of US-guided FNAB was 95.9%, the specificity 100%, the sensitivity 53.8%, the positive predictive value 100%, the negative predictive value 95.6%, the false positive rate 0% and the false negative rate 4.3%. When the cases of suspected of malignancy were evaluated as malignant, the accuracy was 84.6%, the specificity 85.7%, the sensitivity 84.6%, the positive predictive value 36.6%, the negative predictive value 98.2%, the false positive rate 63.3% and the false negative rate 1.7%.Conclusion: US-guided FNAB had quite high diagnostic accuracy and the use of preoperative USguided FNAB singles out a patient who needed surgery and avoided unnecessary surgery.
