COMPARISON OF STRAIN ELASTOGRAPHY AND SHEAR WAVE ELASTOGRAPHY FOR DIFFERENTIATING MALIGNANT FROM BENIGN BREAST MASSES

To compare the diagnostic performance of shear wave and strain elastography in distinguishing benign malignant breast lesions. A prospective study carried out from 20th March 2020 to 2021 at department Radiology Sahiwal, Multan, Lahore. The included women who were lined for surgical excision or core needle biopsy examined using B-mode ultrasound elastography. total 30 female patients with 40 lesions study. Lesions categorized on as 3 BI-RADS 3, 18 4A, 5 4B, 7 4C, 5. After performing a Ultrasound examination, US was done. 14-MHz transducer used obtain high-resolution images. For comparing both, an area under ROI curve (AUC) data sets compared. McNemar test comparison sensitivity specificity both sets. Mean age participants 48.4 years (21-80years). 24 while 16 malignant. B mode imaging showed diameter lesion ranged 0.5 5.2 cm. There no significant difference between elastographic 6 masses discrepant results. category 4a BI-RADs selectively downgraded bases cutoff values, AUCs improvement. Diagnostic is same. Combining has better than each individually.
