S-Detect In Breast Ultrasound on SAMSUNG RS80A
A complementary diagnostic ultrasound technique for imaging elasticity, Elastography, noninvasively assesses the relative tissue stiffness of lesions compared to the stiffness of surrounding tissues to detect suspicious malignant lesions. Stiffer areas hardly deform than do their surroundings and provide dark contrast, whereas softer areas provide light contrast. This technique is normally used as an additional diagnostic tool to differentiate benign from malignant solid breast masses providing information on the mechanical properties, since malignant lesions are generally harder than benign lesions. Breast Elastography can substantially improve ultrasound capability in differentiating benign from malignant breast lesions with increased sensitivity and specifcity of breast ultrasound, thus reducing the number of biopsies. However, the limitation of the Elastography is the inter- /intra-observer variability and lack of standardized compression. To overcome these problems, Samsung Medison developed the semi-quantifcation ElastoScanTM technique, E-BreastTM(ElastoScanTM for Breast), using strain ratio which compares the strain of a region of interest and that of a reference region. E-BreastTM improves classifcation and characterization of benign and malignant breast masses.
