Background; SWE is highly reproducible for assessing elastographic features of breast masses within and across observers. SWE interpretation is at least as consistent as that of BI-RADS ultrasound B-mode features. Aim and objectives; was to assess the role of elastography in diagnosis and differentiation of breast masses. Subjects and methods; this was a Cross sectional study, was carried on all patients admitted to Radiology department, ultrasound unit at Aswan university hospitals, from March 2019 till September 2020. Result; There was a significant difference between the benign and malignant groups in regard to the side and size of the breast masses, while no significant difference was recorded regarding other ultrasonic characteristics as site, surface, surroundings, calcification, and LN. In addition, there was significant difference between the two groups as regard Elastography score (strain ratio). Conclusion; The qualitative and quantitative SWE provided good diagnostic performance in evaluating of malignant and benign masses. The maximum elasticity of the quantitative SWE parameters had the best diagnostic performance.
