Afr. j. radiol."],"abstract":"<jats:p>Background:\u00a0Ultrasound elastography, with the measurement of the lesional width ratio between elasticity imaging (EI) and B-mode image (BI) (EI\/BI), provides a non-invasive method for breast cancer (BC) characterisation. Evidence from a limited number of researchers supporting the efficacy of this ratio in avoiding unnecessary biopsies warrants further exploration.Objectives:\u00a0To assess the role of the EI\/BI ratio in the evaluation of solid breast lesions and correlate the findings with histopathological results.Method:\u00a0The study enrolled 54 female patients with clinically palpable breast lesions, non-palpable breast lesions (seen on mammography or ultrasound) and high-risk female participants with a positive family history of BC. Using ultrasound elastography, the EI\/BI ratio was calculated and correlated with the histology using the Chi-square test and Cramer\u2019s V test.Results:\u00a0The mean age was 41.9 \u00b1 11.8 years, and 59.2% had fibroadenomas. The EI\/BI ratio was \u2265 1 in 16 (29.6%) cases, where malignancy was confirmed on histology in all cases. Thirty-eight cases were benign as per the EI\/BI ratio ( 1), of which 2 were found to be malignant. A significant correlation was seen between the EI\/BI ratio and histopathology findings (p\u00a0 0.001). The specificity, sensitivity, positive and negative predictive values and diagnostic accuracy of the EI\/BI ratio were 100%, 88.9%, 94.7%, 100% and 96.3%, respectively.Conclusion:\u00a0The EI\/BI ratio is effective in differentiating between benign and malignant solid breast lesions, with a statistically significant correlation with histopathology.Contribution:\u00a0The study validates the use of EI\/BI ratio by radiologists to effectively differentiate between benign and malignant breast lesions in patients.<\/jats:p>","DOI":"10.4102\/sajr.v29i1.3158","type":"journal-article","created":{"date-parts":[[2025,7,21]],"date-time":"2025-07-21T07:16:06Z","timestamp":1753082166000},"update-policy":"https:\/\/doi.org\/10.4102\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Role of elasticity imaging\/B-mode imaging ratio in the evaluation of solid breast lesions"],"prefix":"10.4102","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0914-1585","authenticated-orcid":false,"given":"Asif I.","family":"Tamboli","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6258-8140","authenticated-orcid":false,"given":"Abhijit A.","family":"Gadpalliwar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-7243-6002","authenticated-orcid":false,"given":"Raghav","family":"Agarwal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-9818-9523","authenticated-orcid":false,"given":"Chaitali V.","family":"Ukirade","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2580","published-online":{"date-parts":[[2025,7,23]]},"reference":[{"key":"ref0","unstructured":"World Health Organization.
