Elastographic E-values of Benign and Malignant Breast Lesions and Surrounding Tissue

Purpose: Elastography is a new dynamic technique that uses ultrasound to estimate the stiffness of tissues by measuring the degree of distortionand produces real- time quantitative colour- coded map of local tissue elasticity. The aim of this study was to determine and compare benign and malignant breast lesions using shear-wave elastography (SWE). Methods and Materials: We used Aixplorer Supersonic scanner with high-frequency transducer. B- mode and SWE of breast lesions was performed in 254 women, 270 lesions were analyzed. The colour scale indicated tissue elasticity in kilopascals (kPa). Maximum, minimum and mean kPa E-values were recorded in each lesion and surrounding tissues. In malignant lesions SWE area of bright colour was measured and compared with tumour area measured by B-mode. 115 lesions were malignant, as confirmed by core-biopsy, and 155 benign. Results: Maximum value in kPa per malignant lesion was 300 kPa, mininimum 61, 1 kPa and mean 180, 9 kPa.Tissue around malignant lesions had maximum values of 89, 6 kPa, minimum of 2, 5 kPa and mean of 32, 4 kPa. The values in kPA of surrounding tissues around benign lesions were: maximum 62, 1 ; minimum 15, 5 ; mean 30, 6 kPa. Mean area of malignant lesions measured by SWE was 3.81 cm2 (range 1.48-8.59 cm2), and by B-mode 1.6 cm2 (range 0.35-4.4 cm2) (p < 0.01). Conclusions: Malignant lesions have significantly lower elasticity than benign lesions. Area of malignant lesions measured by SWE is significantly larger compared with B-mode measurement. Surrounding tissue around benign lesions is softer as compared to malignant leasions.
