![]() ![]() Ultrasound elastography has 86.5% sensitivity, 89.8% specificity, and 88.3% diagnostic accuracy in the differentiation of benign from malignant solid breast masses. 3 Recent studies show that ultrasonographic elastography (USE) provides higher diagnostic accuracy compared with conventional B-mode ultrasonography during breast cancer diagnosis, which eventually helps to reduce false-positive results (ie, increased specificity) and therefore is useful in avoiding breast biopsy. It increases the specificity of conventional B-mode ultrasound by more precise characterization of breast lesions. Ultrasound elastography provides a non-invasive evaluation of a the “stiffness” of a lesion. The first practical diagnostic equipment was released in 2003.īreast ultrasound elastography is an emerging sonographic imaging technique which provides information on breast lesions in addition to conventional ultrasonography (US) and mammography. 2 In 1997, the first clinical study was published showing the potential of elastography in the detection and characterization of breast lesions. Ophir et al raised the concept of ultrasound elastography in 1991. 1Its high incidence has led to research on new diagnostic imaging techniques for early diagnosis and to improve patient’s mortality rate. Breast cancer alone accounts for 25% of all cancer cases and 15% of all cancer deaths among females. Breast cancer is the most frequently diagnosed cancer and the chief cause of cancer death among women worldwide, with an estimated 1.7 million cases and 521,900 deaths in 2012.
