Ultrasound Elastography is a new imaging technique based on Estimation of the elastic properties of tissues and differentiating Between benign and malignant breast lesions through the Difference in tissue stiffness. Many studies have been performed to determine whether adding Elastography to conventional ultrasound is valuable or not. Results proved high specificity of elastography compared to Conventional ultrasound which may decrease the number of Unnecessary biopsies especially in lesions categorized BIRADS 3 and 4a lesions.The routinely used method for classification of breast lesions according to tissue elasticity is the color coding as well as the strain ratio methods. Ultrasound elastography, does not only have a confirmatory diagnostic tool with sono-mammography, but also can be a beneficial technique by which ultrasound BIRADS downgrading of benign lesions could be elicited, thus reducing the number of unnecessary breast biopsies, and consequently improve the patients compliance .
