Ultrasound plays a key role in the management of thyroid nodules, from diagnosis to follow-up. The Thyroid Imaging Reporting And Data System (TI-RADS) classification is a standardized system for analyzing and reporting thyroid ultrasound data in order to improve nodule management. This 6-grades score is based on ultrasound criteria (shape, contour, aspect, and structure) and aimed at categorizing and depicting carcinomas in a simple and reproducible way. Based on operator-dependent ultrasound examination, the TI-RADS classification has both strengths and limitations.
