Breast shear wave elastography

Emerging ultrasound elasticity imaging techniques have been of great interest as an adjunct to breast sonography to improve its sensitivity and specificity for diagnosis of breast cancer. This chapter focuses on applications of shear wave elastography techniques, more specifically comb‐push ultrasound shear elastography in breast imaging. Elasticity imaging is an emerging field that can noninvasively evaluate the tissue elasticity. Ultrasound‐based elasticity imaging is an emerging field and has been of great interest as an adjunct to breast sonography to improve its sensitivity and specificity for the diagnosis of breast cancer. Shear wave elasticity imaging is the first shear wave elastography method. Shear wave elastography using acoustic radiation force impulse (ARFI) has also been used for differentiation of breast masses. Gray scale ultrasound may underestimate the size of cancerous tumor when compared to actual size at histology.
