Abstract Objective: To evaluate the diagnostic efficacy of TI-RADS in thyroid benign nodules and to evaluate the consistency between observers. Methods: We retrospectively analyzed clinical data and characteristics of preoperative ultrasound of 266 patients with thyroid nodules confirmed by surgery or FNA. All the characteristics of ultrasound were confirmed by two experienced ultrasound physicians, according to the currently accepted standards, including solid composition with low echo or extremely low echo, lobulated and irregular edge, microcalcifications, and aspect ratio>1. All the nodules were divided into 3, 4a, 4b, 4c, 5 classes with pathology as the gold standard. The detection rate of malignant tumor in each classification were analyzed. Results: Two ultrasound physicians were consistent in classification of TI-RADS in thyroid nodules. The detection rates of malignant tumor in TI-RADS 3, 4a, 4b, 4c and 5 were 0%, 5.3%, 33.9%, 52.2% and 100.0%, respectively. Conclusion: TI-RADS has an important guiding significance in ultrasonic evaluation of the benign and malignant thyroid nodules and clinical management.
