It has an ultrasound lexicon, a standard report, definitions of benign, low-, intermediate- and high-risk nodules with the estimated risk of cancer in each, and indications for fine-needle aspiration. Its stated aims are reproducible descriptions between readers and simpler communication of results.","asOf":"2026-11-04","links":[{"label":"Russ et al., European Thyroid Association guidelines for ultrasound malignancy risk stratification of thyroid nodules in adults: the EU-TIRADS (Eur Thyroid J 2017)","url":"https://doi.org/10.1159/000478927"}],"tags":[],"related":["ti-rads","k-tirads","bethesda-category"],"cancers":["thyroid"],"sections":[],"technologies":["ultrasound"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"category":"Diagnostics & imaging"},"route":"/terms/eu-tirads/","neighbours":{"term":[{"id":"bethesda-category","kind":"term","name":"Bethesda category (thyroid cytology)","route":"/terms/bethesda-category/"},{"id":"k-tirads","kind":"term","name":"K-TIRADS (Korean thyroid nodule ultrasound system, 2021)","route":"/terms/k-tirads/"},{"id":"ti-rads","kind":"term","name":"TI-RADS (Thyroid Imaging Reporting and Data System)","route":"/terms/ti-rads/"}],"cancer":[{"id":"thyroid","kind":"cancer","name":"Thyroid cancer","route":"/cancers/thyroid/"}],"technology":[{"id":"ultrasound","kind":"technology","name":"Ultrasound","route":"/technologies/ultrasound/"}]}}
