Abstract

Background: Mammography is criticized for having poor specificity and sensitivity in breast parenchyma that is dense. Additionally, breast cancer risk is higher in women who have dense breast tissue. Tomosynthesis and contrast-enhanced mammography are relatively new imaging methods that have been linked to breast cancer identification and diagnosis. Objective: to evaluate breast lesions using both breast contrast-enhanced mammography and tomosynthesis. Patient and method: 50 patients participated in this prospective trial, and each had single view tomosynthesis and contrast-enhanced mammography. The research was carried out between March 2021 and February 2022 at Mediant AL Tab Hospital & Behia Center's radiological department, and it was authorized by the ethics committee. Specific computer statistical software was used to gather and evaluate the radiological and histopathological findings. Results: Contrast-enhanced mammography was shown to have a 95.5% sensitivity, an 80% specificity, a 97.7% positive predictive value (PPV), and a 66.67% negative predictive value (NPV). Tomosynthesis demonstrated an 88.9% sensitivity, 60.0% specificity, 95.2% PPV, and 37.5 % NPV. Conclusion: Breast contrast-enhanced mammography outperformed tomosynthesis in detection and classification of breast lesion according to BIRADS category, multiplicity (multifocal or multi centric) of lesion, follow up of response to therapy, but in size of lesion no signification different result detected.
