Abstract

Abstract
Background: Asymmetric breast densities are encountered relatively frequently, being reported to occur in 3% of mammogram. In addition, MRI represents the gold standard technique in patients with breast cancer.
Aim of the Work: To detect asymmetric densities identified on mammograms through MRI.
Methodology: This cross sectional study was conducted at the Radiology Department of Aswan University Hospital and the Radiology Department of Aswan Oncology Center. The study population consisted of 65 female patients who had suspected breast lesions based on prior mammography examinations.
Results: The sensitivity of the breast mammography in the breast cancer screening with reference to the pathology results is 52.6%, the specificity is 87%, the positive predictive value is 62.5% and diagnostic accuracy is 76.9%. The sensitivity of the MRI in the breast cancer screening with reference to the pathology results is 100%, the specificity is 78.3%, the positive predictive value is 65.5% and diagnostic accuracy is 84.6%.
Conclusion: breast MRI has higher sensitivity and negative predictive value (both 100%) for breast cancer detection compared to mammography alone
