乳腺钼靶联合磁共振动态增强扫描对含钙化灶的致密型乳腺良恶性病变的鉴别诊断价值OA

Objective To analyze the value of mammography(MG)combined with dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)scan in the differential diagnosis of benign and malignant lesions of dense breast with calcification.Methods 120 patients with dense breast lesions with calcification were divided into the benign group and the malignant group according to the character of the lesions.Both groups were examined by MG and DCE-MRI scan,and the diagnostic efficiencies of single and combined examination for benign and malignant lesions of dense breast with calcification were analyzed.Results MG examination showed that the lesion diameter of the benign group was smaller than that of the malignant group,and the number of lesions was less than that of the malignant group(P<0.05).DCE-MRI scan showed that the scores of shape,edge type,enhancement mode and signal intensity curve of the benign group were lower than those of the malignant group(P<0.05).The sensitivity,specificity and accuracy of MG combined with DCE-MRI scan in the diagnosis of dense breast lesions with calcification were higher than those of MG and DCE-MRI scan(P<0.05).Conclusions MG combined with DCE-MRI scan has high value in the differential diagnosis of benign and malignant lesions of dense breast with calcification.
