Abstract
Background: Breast biopsy remains the gold standard for diagnosis of breast lesions; however, most of the breast specimens reveal benign results. Therefore, in order to avoid unnecessary breast biopsies, noninvasive diagnostic tools have been developed. Ultrasound elastography (USE) is a noninvasive technique which helps in reducing the frequency of breast biopsies.
Aims: The aim of the study was to study the role of ultrasound elastography in differentiation of breast lesions which will ultimately help in better patient diagnosis.
Materials and Methods: In this study, 54 patients with 66 breast lesions were first assessed with sonography and then with USE after obtaining informed patient consent. The examination was carried out in Department of Onco Imaging, Delhi State Cancer Institute, Delhi, India. from July 2011 to February 2012.
Statistical Analysis: Statistical analysis was performed using SPSS software (version 20.0).
Results and Conclusion: The lesions were classified on elastography using scoring system described by Itoh et al., 2006 with elasticity score of 1,2,3 as benign and score of 4 and 5 as malignant. The sensitivity of USE was found to be 88.57% with specificity of 90.32% and positive predictive value of 91.18%. Thus, we conclude that in the present scenario, USE can be used in early diagnosis and differentiation of breast masses into benign and malagnant and henceforth, can be influential in reducing the number of breast biopsies.
