Abstract

Background: Papillary thyroid cancer accounts for 80 to 90% of all thyroid cancers. Papillary thyroid cancer is one of the most common types of thyroid cancer and has a good prognosis if detected and treated early, especially in the encapsulated stage. Objective: Study on the value of elastography ultrasound in the diagnosis of papillary thyroid cancer. Materials and Methods: Short-term study on 50 patients with benign thyroid disease and 52 patients with papillary thyroid cancer. Results: Proportion of Rago 4 was 42,3%, Rago 5 was 40,4% and Rago ≥ was 82,7%. The elasticity ratio at a cutoff point of 3.92 and the shear wave velocity at a cutoff point of 3.1 m/s predict papillary thyroid cancer with sensitivities of 73.1% and 92.3%, and specificities of 98.0% and 80.0%, respectively. Combining the Rago 5 score and the elasticity ratio at a cutoff point of 3.8 provides a predictive value for malignant thyroid nodules with a sensitivity of 95.2% and specificity of 72.8%. Conclusion: Thyroid elastography aids in the screening of papillary thyroid cancer through the Rago score (Rago 4 and 5) and elastography parameters (elasticity ratio ≥ 3.92 and shear wave velocity ≥ 3.1 m/s).
