Correlation of Ultrasound Features in the Birads Scoring System with Fnac Findings of Breast Nodules at Jimma University Medical Center, Jimma: A Facility Based Retrospective Study, Jimma, and Southwestern Ethiopia from March 2025 to August 2025

Abstract

Background: High frequency ultrasonography is a noninvasive method for initial breast nodule assessment. Currently Breast Imaging Reporting and Data System used in risk stratification and guide management. This method reduces unnecessary fine needle aspiration cytology rates, benefiting patients and the healthcare system by reducing burden. Objective: This study aims to determine the effectiveness of ultrasound-based risk stratification by correlating ultrasound findings and pathologic diagnosis at Jimma University comprehensive specialized hospital. Method: Hospital based retrospective cross-sectional study design was conducted on radiologic-pathologic correlation study in patients with ultrasound examination for breast nodules classified based on their American College of Radiology Breast Imaging Reporting and Data System score at Jimma University comprehensive specialized hospital, radiology department from March 2025 to August 2025. Descriptive statistics and Chi-square tests were used to measure the strength and direction of the association between variables. Finally results will be presented in the form of texts, graphs and tables and finding of this result will be disseminated to all relevant stakeholders through presentation and publication. Results: Out of 81 breast nodules examined on ultrasound 65 nodules belonged to BIRADS 3 while 3 and 13 nodules belonged to BIRADS 4 and 5 respectively. On FNAC: 3 were found to be IAC Yokohama C1, 59 were C2, 5 were C3, 4 were C4 and 10 were C5. The sensitivity, specificity, PPV and accuracy value of ultrasound were found to be 92.8%, 95.5%, 81% and 96.2% respectively.
