APPLICATION OF ELASTOGRAPHY FOR DIAGNOSIS BREAST TUMORS

Breast tumor is common in women. Benign tumors account for 80%, malignant tumors account for 20%. Breast cancer is the most common and deadly cancer among women, including Vietnam. Elastography, evaluates the stiffness of the tissue, helps to distinguish soft or hard tumors, which can help distinguish benign or malignant. Benign lesions tend to be softer than malignant lesions. There are two types of elastography: SE (Strain Elastography) and Shear Ware Elastography (SWE). In examining breast lesions, the maligne tumor tends to be stronger and the higher the velocity. Studies have shown that the SWE features should be combined with 2D ultrasound to complement the BIRADS classification. Elastography is a new technique that has emerged in the past few years, promising good diagnostic prospects, more and more research and application of elastography in diagnostics breast lesions. Breast elastogarphy, survey of hardness of breast cancer showed 4 times higher than that of benign tumor and 7 folds of normal breast tissue.
