A new thyroid imaging reporting and data system for nodules: Based on grayscale and color Doppler ultrasonography.

Objective: To construct and validate a new thyroid imaging reporting and data system (TI-RADS) based on radiating blood flow and grayscale US features.

Materials And Methods: This study enrolled patients from 4 hospitals from January 2018 to November 2023 retrospectively and prospectively. All US features associated with malignant thyroid nodules were assessed by multivariable logistic regression to construct baseline US TI-RADS (BUS TI-RADS), which was tested with internal validation set, external validation set and prospective validation set.

Radiating blood flow signal: A new ultrasound feature of thyroid carcinoma.

Objective: To summary radiating blood flow signals and evaluate their diagnostic value in differentiating benign and malignant thyroid nodules.

Materials And Methods: We retrospectively recruited consecutive patients undergoing US at 4 hospitals from 2018 to 2022. In a training dataset, the correlations of US features with malignant thyroid nodules were assessed by multivariate logistic analysis.
