AbstractIntroduction: Globally, breast cancer is the leading cause of cancer-related mortality for women and the most common malignancy in terms of diagnoses. Early detection of breast cancer is key to its optimum management and control. Noninvasive imaging methods for the diagnosis of breast lesions include MR mammography and sonoelastography. Determining the efficacy of dynamic MR mammography and sonoelastography in assessing breast masses with BIRADS-III or higher lesion categories was the aim of this study.
Materials and Methods: Forty-eight female patients with breast cancer older than 28 years old, clinically and histopathologically diagnosed, were included. Each subject underwent a typical B mode ultrasonography. Sonoelastography was employed to assess patients with lesion types BIRADS-III and above, and dynamic contrast enhances MR mammography. A 1.5 Tesla GE MRI was utilized to perform MR mammography. Axial and sagittal T1 and T2 WI, DWI, and axial STIR sequences were used.
Results: Histopathological examination showed benign lesion in 62.5% and malignant in 37.5% of cases. The predictive validity of MRI curve category exhibited the sensitivity, specificity, PPV, NPV and Diagnostic accuracy was 92.4%, 96.1%, 98.3%, 94%, and 95.7% respectively. Whereas for sonoelastrography grading, the sensitivity, specificity, PPV, NPV and Diagnostic accuracy was 80.9%, 92.8%, 90.2%, 84.31% and 82.6%.
Conclusion: sonoelastography and MR mammography are good diagnostic methods for breast lesions, according to the results, while MR mammography has higher diagnostic accuracy, sensitivity, and specificity.
