Elastography is a technique that adds the basic mechanical information of “elasticity” to the previous ultrasound reflection of the morphological structure of the lesion, and obtains information about the hardness or elasticity of the tissue through ultrasound and forms elastic images with the help of color coding. With the use of elastography, doctors can do quantitative and semi-quantitative analysis of elastic images on the basis of the main information (such as the size, boundary, morphology, internal and peripheral blood flow of the lesion) that can be provided by the traditional examination of breast diseases, so as to obtain more information about the diseased tissue, reduce the influence of human factors on the diagnosis of diseases, significantly improve the sensitivity, specificity and accuracy of the diagnosis of breast lumps, and improve the diagnosis of early breast cancer. It is of positive significance to detect early breast cancer, reduce patients’ pain and improve their quality of life.
