The European Thyroid Association (ETA) has developed the EU-TIRADS (European Thyroid Imaging and Reporting Data System) to provide a standardized approach for risk stratification of thyroid nodules using ultrasound. This system aims to enhance interobserver reproducibility and simplify communication of results. The EU-TIRADS includes a structured report, a lexicon, and a scoring method. Nodules are categorized into five risk groups (EU-TIRADS 1-5) based on their ultrasound features, with corresponding recommendations for fine needle aspiration (FNA) biopsy. The system emphasizes the importance of combining multiple ultrasound features to improve diagnostic accuracy. The guidelines also address other ultrasound findings such as suspicious lymphadenopathy, extrathyroidal extension, macrocalcifications, hyperechoic spots, and vascularity. The task force recommends against routine Doppler ultrasound and elastography for risk stratification but suggests their use as complementary tools. The EU-TIRADS is designed to guide clinical decision-making and reduce unnecessary FNA procedures.The European Thyroid Association (ETA) has developed the EU-TIRADS (European Thyroid Imaging and Reporting Data System) to provide a standardized approach for risk stratification of thyroid nodules using ultrasound.
