摘要

Purpose

The purpose of this study was to compare the value of contrast-enhanced ultrasound (CEUS) plus MicroFlow Imaging (CEUS-MFI), MicroFlow Imaging (MFI) alone, and color Doppler flow imaging (CDFI) in the differential diagnosis of benign and malignant breast lesions.

Methods

A total of 116 patients with 116 breast lesions categorized as Breast Imaging Reporting and Data System (BI-RADS) category 4 were enrolled in this prospective study. CEUS-MFI, MFI, and CDFI were used to evaluate the microvascular morphology and distribution types of breast lesions. Pathological results were considered the gold standard.

Results

Compared with conventional CDFI and MFI, the CEUS-MFI technique can reveal microvasculature and distribution types at a higher resolution in breast masses. The sensitivity, specificity, and accuracy of CEUS-MFI were 96.3%, 80.6%, and 91.4%, respectively. The sensitivity, specificity, and accuracy of MFI were 87.5%, 75.0%, and 83.6%, respectively. The sensitivity, specificity, and accuracy of CDFI were 58.8%, 72.2%, and 62.9%, respectively. The accuracy was significantly different between CEUS-MFI and MFI (P = 0.024), and the accuracy was significantly different between CEUS-MFI and CDFI (P = 0.000). US BI-RADS 4A masses were downgraded based on CEUS-MFI features without any malignancy missed, with the biopsy rate decreasing from 100% (29/29) to 31.0% (9/29).

Conclusion

CEUS-MFI provides improved diagnostic efficacy for breast lesions. The CEUS-MFI technique can be used as an effective supplement to conventional ultrasound in the diagnosis of breast tumors.
