DIGITAL BREAST TOMOSYNTHESIS AND DIGITAL MAMMOGRAPHY FOR BREAST CANCER DIAGNOSIS

Purpose:- To compare the diagnostic performance of digital breast tomosynthesis (DBT) and digital mammography (DM) for breast cancer. Materials and Methods: Ninety patients from December 2013 till December 2015 were enrolled in the study. All patients had pathologically proven cancer. Assessment of the lesions based upon digital tomosynthesis, compared with digital mammography (DM) and correlated with the pathological results. Results: BT shows better detection of malignant speculated masses (75% on DCI, 76.47% on ILC, 84.38% on IDC compared with (12.5%, 41.18%, 67.19% on DM respectively). Fourteen malignant masses were clearly visible on BT while were questionably visible on DM. BT changes BIRADS classification from IV to V in 22 patients (24.44% more accurate; 81.11/56.66%)). Conclusion: Tomosynthesis improves the detection and characterization of breast masses, especially in dense breast.
