Thyroid Imaging Reporting and Data System (TIRADS)

Ultrasound (US) is the best diagnostic choice for thyroid nodules. Recently, the thyroid imaging reporting and data system (TIRADS) has been developed for risk stratification of thyroid nodules using various US features, similar to Breast Imaging Reporting and Data System (BI-RADS) for evaluating breast lesions. The reporting system can allow effective communication between the reporting doctors, such as radiologists, cytologists, and clinicians using standardization and simplification of the reports. In this review, I discuss several TIRADS systems developed.


Thyroid nodule; Ultrasonography; TIRADS; Fine needle aspiration
