Abstract:
OBJECTIVES:The purpose was to evaluate whether BI-RADS (the Breast Imaging Recording and Data System) combined with UE (ultrasound elastography) could improve the differentiation and characterization of benign and malignant breast lesions by comparing with BI-RADS. METHODS:A total of 1080 patients with 1194 breast lesions were studied retrospectively at 8 different institutions from 3 geographic areas across China (North, South, and West) from June 2010 to March 2012. Each institutional ethic review board approved the study and all patients gave written informed consent. All the cases were examined by conventional US (ultrasonography) and UE prior to ultrasound-guided core biopsy. Performance of BI-RADS and BI-RADS combined with UE were compared in different size groups, age groups and area groups. RESULTS:BI-RADS combined with UE cloud improve the accuracy by 13.2% compared to BI-RADS alone for all lesions, 23.2% for <10 mm lesions, 13.3% for ≥10-20 mm lesions, 6.3% for ≥20 mm lesions, 18.4% for <50 years group, 1.7% for ≥50 years group, 13.7% for northern area group, 17.7% for southern area group and 4.4% for western area group. CONCLUSIONS:The help which UE contributed to BI-RADS was greater for breast lesions <10mm and <50 years group.
