VALUE OF SHEAR WAVE ELASTOGRAPHY IN DIAGNOSIS OF BREAST CANCER
Main Article Content
Abstract
Objective: The purpose of this study was to evaluate the value of shear wave elastography (SWE) in diagnosis of benign and malignant breast lesions. Methods: 60 women with 62 breast tumors were evaluated by B – mode ultrasound and shear wave elastography .The breast lesions were classified by US breast imaging reporting and data system (BI-RADS) category 3,4a/b/c,5. The maximum, minimum, mean and median shear wave velocity (SWV) values in the lesions were obtained. From that, evaluated the sensitivity, specificity and cut – off of the shear wave elastography for diagnosis of benign and malignant breast lesions. Results: 60 women with 62 breast lesions, diagnosed by histopathology. Fifteen of 62 lesions were malignant and 47 were benign. The mean SWV (5.85 ± 1.18 m/sec vs 2.61 ± 0.52m m/sec) for malignant lesions and benign lesions. The cut-off value of mean SWV was 3.79 m/s, with sensitivity and specificity of 100% and 95.7% respectively. Conclusion: Using SWE with high sensitivity, specificity in diagnosis of benign and malignant breast lesions. SWE is useful in differentiating malignant from benign breast lesions.
