SonoAtlas NoduleSim™Thyroid Edition

An interactive thyroid nodule risk-stratification simulator. Sculpt the nodule's sonographic features, watch it redraw in both transverse and longitudinal planes, and see how ACR TI-RADS, K-TIRADS, EU-TIRADS, and ATA guidelines each classify the same lesion.

Simulated Ultrasound Appearance

Same nodule shown in two planes. Schematic — intended to teach feature recognition, not to replace real sonographic images.

Pearl: Shape (wider-than-tall vs taller-than-wide) is assessed in the transverse plane only. Longitudinal confirms margin, composition, and foci but does not contribute to shape scoring.

Scoring references: ACR TI-RADS (Tessler FN, J Am Coll Radiol 2017;14:587–595; refined 2024). K-TIRADS (Ha EJ et al, Korean J Radiol 2021;22:2094–2123). EU-TIRADS (Russ G et al, Eur Thyroid J 2017;6:225–237). ATA 2015 (Haugen BR et al, Thyroid 2016;26:1–133). This tool is an educational aid — clinical decisions require the complete sonographic exam, patient history, and radiologist judgment.
