摘　　要：目的评价动态增强MRI对乳腺良恶性病变的诊断价值。方法对60例经手术病理证实的乳腺疾病患者行MRI平扫和动态增强检查。结果28例乳腺癌的形态学特征性表现有形态不规则、环形强化和毛刺征。32例乳腺良性病变特征性表现有类圆形或分叶状,边缘光整,强化均匀及强化后可见低信号间隔。良恶性病变T1WI和T2WI信号强度无显著性差异(P>0.05);良恶性病变增强后边缘形态分布差异有显著性(P<0.01);良恶性组间早期强化率差异有显著性(P<0.01);对乳腺癌诊断的敏感性为67.9%、特异性为77.8%、准确性为72.5%。结论MRI动态增强减影技术对乳腺癌的诊断有一定的诊断价值,值得在临床上推广应用。Objective To evaluate the diagnostic value of benign and malignant in breast lesions by enhanced MRI. Methods 60 cases confirmed by surgery and pathology of the disease in patients with breast by MRI scan and dynamic enhanced inspections. Resuls The morphological features of the breast cancer performance irregular shape, strengthen and Burr ring levy. Benign breast lesions characteristic of a round or sub-fronds,whole-edge,strengthen and intensify after the uniform that low signal spacing. Benign and malignant lesions T1WI and T2WI signal strength no significant difference（P〉0.05）; benign and malignant lesions enhanced edge of species distribution there were significant differences （P〈0.01）; benign and malignant group early enhancement were significant differences （P〈 0.01 ）; breast cancer diagnosis rate of sensitivity,specifity and accuracy were 67.9%,77.8% and 72.5%. Conclusion MRI dynamic enhanced by video technology in the diagnosis of breast cancer have a certain value.
