摘　　要：目的研究MR动态增强及减影成像鉴别乳腺良恶性病变的价值。方法统计分析我市各医院影像中心2007年1月至2014年6月收治的172例乳腺疾病患者的临床资料。结果 172例182个病灶经病理证实,其中100例102个病灶为恶性,6例6个病灶为重度不典型增生癌变伴浸润,66例74个病灶为良性;乳腺恶性病变组患者的单向型、平台型比例均显著低于良性病变组(P<0.05),流出型比例显著高于良性病变组(P<0.05),肿瘤血管数目0支比例显著低于良性病变组(P<0.05),1支、多支比例均显著高于良性病变组(P<0.05),乳腺良恶性肿瘤的形态学体征和间接征象之间的差异均显著(P<0.05)。结论 MR动态增强及减影成像鉴别乳腺良恶性病变具有较高的价值。Objective To study the value of MR dynamic contrast-enhanced and subtraction imaging study in the identification of benign and malignant breast lesions. Methods The clinical data of 86 cases of breast disease patients who were treated in City hospitals Imaging Center from January 2007 to June 2014 were statistically analyzed. Results Among the 172 cases 182 pathologically confirmed lesions, 100 cases 102 lesions were malignant, 6 cases 6 severe dysplasia lesions were invasive cancer, 66 cases 74 lesions were benign; the proportion of malignant breast lesions with unidirectional , platform type were significantly lower（P〈0.05）, the outflow proportional was significantly higher than the benign group （P〈0.05）, the ratio of the number of tumor vessels 0 was significantly lower （P〈0.05）, the proportion of 1, multivessel disease were significantly higher than benign group（P〈0.05）, the differences of signs and indirect signs between benign and malignant breast morphology were significantly （P〈0.05）.Conclusions The value of MR dynamic contrast-enhanced and subtraction imaging is high in the identification of benign and malignant breast lesions.
