Abstract
Elastography is an easy procedure with high diagnostic performance which can be easily integrated with the B-mode ultrasound examination in the same session and improves its specificity. It has proven benefit in minimizing the number o unnecessary biopsies especially in the assessment of BIRADS 3 and 4a lesions Elastography is an imaging technique that refers to the measurement of elastic properties of tissues, based on the well established principle that malignant tissue is harder than normal and benign tissues. It measures the relative stiffness of lesions in contrast to the surrounding normal tissue, the information displayed in the images are a surrogate for that obtained with manual palpation. The technique is typically performed with ultrasound, but researches with magnetic resonance imaging are also ongoing. Several studies have been performed on elastography aiming to improve ultrasound specificity in differentiating between benign and malignant lesions hence help to reduce the number of unnecessary biopsies. Elastography is performed in the same clinical setting with conventional B-mode breast ultrasonography. Images are produced prior to and post slight axial compression with the ultrasound probe, then image are displayed either by the lesion size comparison method or the color coding method.
