Purpose
To evaluate sensitivity and specificity of supersonic shear wave imaging quantitative elastography (SSI) for distinguishing benign and malignant solid breast masses.Materials and methods
100 patients with small solid breast masses, were included. The lesions were classified according to the BIRADS (Breast Imaging and Reporting Data System) by SSI. Measurement of the kilopascals (kPa) in different areas of the examined region of interest (ROI) was performed. Ultrasound-guided Tru-cut needle biopsy with an 18-gauge needle was done in all cases.
Results
From the malignant lesions (according to histopathological data), 15 % were classified as BIRADS 4 and 85 % as BIRADS 5 by SSI. Of the benign lesions, 98 % , were classified as BIRADS 3 % and 2 % as BIRADS 4. According to the histological data, 100 % of the lesions with a score of 5 (by SSI) were malignant and 100 % of the lesions with a score of 3 were benign. 10 % of the lesions with a score of 4 were benign and 90 % were malignant. The mean elasticity values were significantly higher for malignant lesions than for benign lesions.
Conclusions
SSI has high sensitivity and specificity in the differentiation of benign and malignant solid breast masses.
