Abstract：ObjectiveTo explore the value of elastography in the guidance of ultrasound-guided breast mass biopsy.MethodsA total of 140 patients with breast mass biopsy were enrolled. The patients underwent routine ultrasound and elastography from February 2017 to December 2018, and applied with BI-RADS classification and elasticity scores. The benign and malignant nature of the patient's breast mass were evaluated.ResultsAmong 140 cases, 68 cases (48.57%) were benign lesions, 43 cases (30.71%) were fibroadenoma and 12 cases (8.57%) were intraductal papilloma. Malignant lesions were found in 72 cases (51.43%) and invasive ductal carcinoma in 48 cases (34.29%). After BI-RADS grading, the sensitivity, specificity and accuracy were 93.06% (67/72), 61.76% (42/68) and 77.86% (109/140), respectively. After elastic score diagnosis, the sensitivity, specificity and accuracy were 87.5% (63/72), 89.71% (61/68) and 88.57% (124/140), respectively. The difference of sensitivity was not significant (P>0.05). The difference of specificity and accuracy between groups was significant (P<0.05).ConclusionColor doppler ultrasound with different elasticity scores evaluates breast masses above grade 4. Its clinical decision-making needs to be treated differently to improve its diagnostic accuracy.
