ABSTRACT
BACKGROUND:
Breast cancer is the most common malignant tumor in women. Early diagnosis of benign and malignant breast tumors is of great significance.OBJECTIVE:
To retrospectively analyze the value of contrast-enhanced ultrasonography (CEUS) in the diagnosis of Breast Imaging-Reporting and Data System (BI-RADS) 4a breast lesions less than 2âcm in diameter.METHODS:
CEUS was performed for 143 breast masses less than 2âcm in diameter that were diagnosed as BI-RADS 4a by ultrasound and reclassified. Considering pathological diagnosis as the gold standard, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of reclassified lesions after CEUS for the diagnosis of benign and malignant masses were analyzed.RESULTS:
BI-RADS 4a breast masses with a diameter less than 2âcm (nâ=â143) were confirmed by pathology; 103 and 40 were classified as benign and malignant, respectively. The sensitivity, specificity, PPV, and NPV of CEUS for the diagnosis were 90%, 86%, 72%, and 95%, respectively. The area under the receiver operating characteristic (ROC) curve of CEUS for the diagnosis of benign and malignant tumors after CEUS was 0.904.CONCLUSION:
CEUS can help to improve the diagnostic accuracy of BI-RADS 4a masses with a diameter less than 2âcm.Palavras-chave
