jectives: To describe some clinical features of thyroid nodules, B-mode ultrasound, Doppler and strain elastography in order to differentiate benign from malignant tumors. Subjects and methods: 72 patients with thyroid nodules were performed clinical examination, 2D ultrasound, Doppler and strain elastography for qualitative assessment of the stiffness of thyroid tumors according to Asteria scores (2008) from ES1 - ES4, semi-quantitative calculating elasticity of the tumors (E2) and normal parenchyma (E1), strain ratio: SR = E2/E1, comparing with fine needle aspiration results.
