    Background:Ultrasound based risk stratification is a widely used method currently helping to guide management in patients with thyroid nodules; which are common and mostly benign. The use of these risk stratification methods has helped reduce unnecessary FNAC rates, therefore, reducing the burden both on patients and the health care system. This study aims to determine the effectiveness of ultrasound-based risk stratification by correlating ultrasound findings and pathologic diagnosis at TikurAnbessa specialized hospital (TASH). Methodology:This was a hospital based prospective radiologic pathologic correlation study in patients referred for ultrasound guided FNAC based on their American College of Radiology Thyroid Imaging, Reporting and Data System (ACR-TIRADS) score at TikurAnbessa Specialized Referral and Teaching Hospital, radiology department, during the time period of April-September 2023 to assess accuracy of ACR-TIRADS in ultrasound based thyroid nodule risk stratification in our hospital. Sixty two patients with thyroid nodules were subjected to ultrasound and USG guided FNAC. Each was assigned a TIRADS and Bethesda category. The outcomes were contrasted in order to assess the ultrasound's sensitivity, specificity, and positive predictive value (PPV) in terms of distinguishing benign from malignant nodules. RESULT: Twenty-six of the sixty-two nodules that were analyzed classified into TIRADS 3, and thirteen and twenty-three, respectively, into TIRADS 4 and 5. On FNAC, 36 were found to be Bethesda 2 & 5, 7, 1 and 8 to Bethesda 3, 4, 5 and 6 respectively. The sensitivity, specificity and PPV of ultrasound were found to be 93.75, 54.35, and 41.67 % respectively.
