Abstract:
Objective To assess the value of contrast-enhanced ultrasound (CEUS) in differential diagnosis of BI-RADS-US 4 breast lesions.Methods A total of 123 lesions underwent CEUS.The CEUS features of lesions were categorized into 5 malignant or benign indexes respectively,lesions displaying any two of the five features were diagnosed as malignant or benign.The diagnostic effect of CEUS for BI-RADS-US 4 lesion was analyzed according to the pathological results as the gold standard.Results CEUS of the 123 BI-RADS-US 4 breast lesions indicated that 75 lesions were malignant while 48 were benign.Pathological results confirmed that there were 72 malignant lesions and 51 benign.The proportions of malignant lesions in 4A category,4B category and 4C category were 16.2 ％,58.5 ％ and 93.3 ％ respectively.The accuracy,sensitivity,specificity,positive predictive value,and negative and positive predictive value of CEUS for the diagnosis of BI-RADS-US 4 lesions were calculated as 92.7％,95.8％,88.2％,92.0％ and 93.7 ％ respectively.Lesions showing false positive in CEUS mainly needed surgical treatment,such as fibroma with active growth mesen-chyme,intraductal papilloma and granulomatous mastitts.Conclusions Surgical treatment rather than aspiration biopsy are suggested for those diagnosed being malignant in CEUS of the BI-RADS-US-4 lesions,as they can be treated as BI-RADS5 lesions.Short-term visit or aspiration biopsy are suggested for BI-RADS-US-4 lesions diagnosed being benign in CEUS.
