STUDYING THE VALUE OF ULTRASOUND BASED ON THE TI-RADS ACR 2017 CLASSIFICATION IN DIAGNOSIS OF THYROID NODULES AT CAN THO ONCOLOGY HOSPITAL 2020-2022
Main Article Content
Abstract
Background: The incidence of thyroid nodules has increased in recent years and is mainly detected by ultrasound. The ACR TI-RADS 2017 classification is a valuable system that helps in classifying risks, recommendations for FNA or ultrasound follow-up. Objectives: Determining the characteristics of ultrasound images of thyroid nodules based on the TI-RADS ACR 2017 classification and the value of the system in the diagnosis of thyroid nodules with pathological comparison. Materials and method: All patients with thyroid nodules were resected at Can Tho Oncology Hospital. Prospective, descriptive cross-sectional study. Results: The study was conducted on 175 patients and 211 thyroid nodules with an average age of 41.9 ± 11.4, the female/male ratio is 5.0. Pathological results were 162 malignant thyroid nodules (76.8%) and 49 benign thyroid nodules (23.2%). The malignancy risk of thyroid nodules increased gradually according to the TI-RADS classification and the scores of TR1, TR2, TR3, TR4 and TR5 respectively 0%, 0%, 1.9%, 34.6% and 63.6%. The TI-RADS ACR 2017 classification has sensitivity, specificity, positive predictive value, negative predictive value and accuracy respectively 98.1%, 79.6%, 92.9%, 94.1% and 93.8%. Conclusion: There is a match between the ACR TIRADS 2017 classification and pathological results with statistical significance with p <0,001
