Abstract
Objective: To evaluate the role of breast digital tomosynthesis mammography in diagnosing BI-RADS 3 and 4 lesions.
Methods: A prospective study was conducted on 100 patients with breast lesions of BI-RADS 3 and 4 on digital tomosynthesis mammography. All patients had histopathologic finding as benign or malignant.
Results: 3D mammography had higher sensitivity and specificity than 2D mammography (93.8% and 94.2% on 3D mammography vs. 85.4%; 84.6% on 2D mammography, respectively. The agreement in BI-RADS 3 and 4 classification on 2D mammograms and 3D mammograms was at a decent level (Cohen’s Kappa = 0.64). The ability to distinguish benign/malignant breast tumors of 3D mammography was at a very good level (0.93), while 2D mammography was at a good level (0.85). Especially in patients with dense breast tissue, 3D mammography had higher sensitivity and specificity of 95% and 95.8%, respectively, than 2D those in mammography (sensitivity: 85.4% and specificity: 87.2%).
Conclusion: 3D mammograms have the ability to distinguish benign/malignant breast tumors better than 2D mammograms. 3D mammography should be considered in combination with or instead of 2D mammography in diagnosing breast lesions, especially in cases with dense breast tissue.
