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.
