Abstract :

Introduction: Ultrasound (US) elastography is an emerging technique that can be used during east US examination. Guidelines recommend mammographic screening and US for diagnosis of east cancer. The specificity of these techniques is not high enough to prevent unnecessary biopsies. Hence there is need for a more specific technique to overcome this problem. This study aimed to evaluate the value of strain elastography (SE) for east lesions. Materials and Methods: In this cross sectional observational study over 18 months, 60 women with palpable east lumps were evaluated with conventional US and SE. Results obtained were correlated with histopathological findings for statistical analysis. Result: A statistically significant correlation was found between SE and histopathological outcome with a p value of 0.03(<0.05). The positive predictive value (PPV) was 76.92% and the negative predictive value (NPV) was 76.47% with Chi square= 8.4. Conclusion: Ultrasound with SE can substantially improve the possibility of differentiating benign from malignant east lesions thereby limiting recourse to biopsy and considerably reducing the number of benign east biopsy diagnoses.
