Abstract:

Objective

To explore the value of contrast-enhanced ultrasound (CEUS) scores, ultrasonic elastography (UE) and their combined scores in diagnosing breast lesions of breast imaging reporting and data system (BI-RADS) 3-4.

Methods

From October 2015 to March 2016, 60 BI-RADS 3-4 solid breast masses diagnosed by conventional ultrasound underwent UE and CEUS. According to the relevant indicators, all cases were scored and proved by surgical pathology. The diagnostic sensitivity, specificity and accuracy of CEUS scores, UE and their combined scores were evaluated, and the receiver operating characteristic (ROC) curve was drawn.

Results

Twenty-nine benign and 31 malignant lesions were confirmed by pathology. The area under the ROC curve of CEUS combined with UE scores was 0.971 which was higher than that of CEUS Scores and UE alone (0.916 and 0.908, respectively). Moreover, the sensitivity, specificity and accuracy were 87.1%, 96.6% and 92.0% for CEUS combined with UE Scores, 77.4%, 93.1% and 85.0% for CEUS Scores, 74.2%, 93.1% and 83.3% for UE, respectively.

Conclusion

CEUS combined with UE scores can improve the differetial diagnostic accuracy for BI-RADS 3-4 breast lesions.
