摘　　要：目的 探讨磁共振成像(MRI)多序列扫描鉴别乳腺小肿块性质的价值。方法 选取我院收治的经病理检查确诊的85例乳腺小肿块患者为对象,均进行乳腺MRI检查,分析MRI平扫序列以及动态增强扫描(DCE-MRI)序列在乳腺小肿块病变良恶性鉴别中的价值。结果 85例患者共90个乳腺小肿块病灶,病理检查显示恶性病灶56个,良性病灶34例。乳腺小肿块良恶性病变的MRI平扫序列信号特点无显著差异(P>0.05)。DCE-MRI序列扫描显示,乳腺小肿块恶性病变的边缘、内部强化、TIC类型与良性病变比较,差异显著(P <0.05)。DCE-MRI诊断乳腺小肿块恶性病变的敏感度为91.07%,特异度为88.24%,阳性预测值为92.73%,阴性预测值为79.31%,准确度为92.22%。结论 DCE-MRI序列可提高乳腺小肿块病变的检出率,在鉴别肿块性质方面价值较高。Objective To explore the value of multi-sequence scanning of magnetic resonance imaging(MRI) in differentiating the nature of small breast masses.Methods 85 patients with small breast masses diagnosed by pathological examination in our hospital were selected as research objects.All cases underwent breast MRI examination,and the value of MRI plain scan sequence and dynamic contrast-enhanced scan(DCE-MRI) sequence in the differentiation of benign and malignant breast small masses were analyzed.Results 90lesions of small breast masses were found in 85 patients.Pathological examination showed 56 malignant lesions and 34 benign lesions.There was no significant difference in the signal characteristics of MRI plain scan sequence between benign and malignant lesions of small breast masses(P >0.05).DCE-MRI sequence scan showed that,there were significant differences in the margin,internal enhancement and TIC type of malignant lesions of small breast masses compared with benign lesions(P <0.05).The sensitivity of DCE-MRI in diagnosing malignant lesions of small breast masses was 91.07%,the specificity was 88.24%,the positive predictive value was 92.73%,the negative predictive value was 79.31%,and the accuracy was 92.22%.Conclusions DCE-MRI sequence can improve the detection rate of lesions of small breast masses,and is of high value in identifying the nature of the mass.
