Abstract

The study was conducted with the objective of evaluating the diagnostic value of ultrasound based on the ACR TI-RADS 2019 classification in the assessment of thyroid nodules. A total of 180 patients with thyroid nodules were enrolled, all of whom underwent thyroid ultrasound and fine-needle aspiration (FNA) with cytological results available. The study was carried out at Ha Tinh city Medical Center from December 2022 to May 2024. Ultrasonographic features of the thyroid nodules were analyzed, classified according to ACR TI-RADS 2019, and subsequently compared with cytopathological findings to assess diagnostic performance. Results: We collected data on 350 thyroid nodules that underwent fine-needle aspiration with available cytological results. The majority of patients were female, accounting for 82.87%. The mean patient age was 46.50 ± 12.45 years, and the average nodule size was 2.11 ± 1.15 cm. The malignancy rate based on cytology was 80.85%, while the malignancy rate according to ACR TI-RADS classification was 83.43%. Specifically, the malignancy risks for TI-RADS categories 2, 3, 4, and 5, when compared with the Bethesda system, were 0%, 0%, 95.61%, and 98.85%, respectively. The agreement between the ACR TI-RADS and Bethesda classifications was very good, with a Kappa coefficient of 0.84. Conclusion: The ACR TI-RADS classification is valuable in assessing the malignancy risk of thyroid nodules, demonstrating a high level of agreement with the Bethesda cytological classification.
