TI-RADS scores a thyroid nodule on ultrasound by its appearance and uses the score to decide whether it needs a needle biopsy, a repeat scan or nothing more.
Most thyroid nodules are benign. The American College of Radiology convened committees in 2012 to write management advice for nodules found incidentally, a standard ultrasound vocabulary, and a risk system built on that vocabulary; the ACR TI-RADS white paper (Tessler and colleagues, JACR 2017) sets out which nodules warrant biopsy or follow-up ultrasound on the basis of their appearance. The ACR's teaching material scores composition, echogenicity, shape, margin and echogenic foci to reach the risk level, with the aim of cutting biopsies of benign nodules.
The name follows BI-RADS. Other societies publish their own versions: the European EU-TIRADS and the Korean K-TIRADS. A nodule that is biopsied is then reported in the Bethesda system.
