Contrast-enhanced ultrasound and ultrasonic elastography in diagnosis of breast tumor / 中国基层医药

ABSTRACT

Objective To evaluate the value of contrast-enhanced ultrasound and ultrasonic elastography in the diagnosis of breast lesions with BI -RADS Ⅲ -Ⅴ.Methods 169 patients with BI -RADS Ⅲ -Ⅴ breast lesions were underwent contrast -enhanced ultrasound and ultrasonic elastography 1 week before surgery.Pathological findings were used as the gold standard to evaluate the diagnostic accuracy of contrast -enhanced ultrasound and ultrasonic elastography in diagnosis of BI -RADS Ⅲ -Ⅴ breast lesions.Results The combination of contrast -enhanced ultrasound and ultrasonic elastography in diagnosis of BI -RADS Ⅲ -Ⅴ breast lesions,with the sensitivi-ty,specificity and accuracy of 96.15%,94.34%,and 95.11%,respectively.The difference was statistical signifi-cance compared with single method(χ2 =4.659,P =0.032,χ2 =4.146,P =0.041).Conclusion The combination of contrast -enhanced ultrasound and ultrasonic elastography improves the diagnostic accuracy of Ⅲ-Ⅴ breast lesions.
