[The role of radiologists in the management of thyroid nodules]

Abstract

We review the different techniques in the diagnostic of thyroid nodule. The ultrasound and, especially, sonographically guided fine-needle aspiration (US-FNA), are the most accurate diagnostics tests to achieve a correct diagnosis of thyroid nodule, which is only done better by the surgery treatment and the pathology study of all lesion. We review the situations in which US-FNA is necessary and the different diagnostic and therapeutics options. Finally, we propose algorithms for the management of a solitary thyroid nodule, multinodular goiter and casually discovered nodule.
