Abstract

The rate of detection of thyroid carcinoma has increased with the widespread use of ultrasonography (US). The role of US has become increasingly important for assessing malignancy risk, fine-needle aspiration (FNA) decision, and management decision after FNA in patients with thyroid nodules. US also has an important role in preoperative staging and postoperative surveillance in patients with thyroid cancer. Many international society guidelines have been recently updated for a more personalized management strategy. Most international society guidelines propose risk stratification systems based on US patterns of thyroid nodules. Although they have similar US criteria and size cutoff for FNA, there are some differences in the sensitivity and specificity of FNA criteria for the diagnosis of thyroid cancer. The clinically feasible and accurate US risk stratification system needs to be standardized in the future. Most current international guidelines suggest more potentiated roles of US in the management of thyroid nodules after FNA, and agree that US has an essential role in preoperative staging and postoperative surveillance in patients with thyroid cancer.
