摘要
目的:探讨MRI动态增强血管成像在乳腺良恶性病变诊断中价值,提高正确诊断率。方法:收集符合标准的患者60例,分析MRI动态增强资料。结果:60例患者病理结果显示乳腺恶性肿瘤37例、乳腺良性病变23例;MRI动态增强诊断正确51例,敏感性86.84%,特异性81.82%。乳腺恶性病变时间-信号强度曲线以Ⅲ型为主(70.27%),乳腺良性病变以Ⅰ型为主(73.91%),差异有统计学意义(P<0.05)。乳腺恶性病变早期强化率和峰值强化率均高于乳腺良性病变,差异有统计学意义(P<0.05)。结论:MRI动态增强血管成像能显示乳腺肿块的形态学和血流动力学特征,具有较高的敏感性及特异性,为乳腺病变定性诊断及治疗提供重要的依据。
Objective：To investigate the values of dynamic contrast enhanced MRI in diagnosis of diseases of mammary gland and to elevate the correct diagnosis percentage .Method：60 eligible patients were enrolled and the dynamic contrast enhanced MRI data was analyzed .Result：As diagnosed by the pathologic results,37 of the 60 patients had malignant tumors of mammary gland , and 23 cases had benign lesions of mammary gland;51 cases were correctly diagnosed by dynamic contrast enhanced MRI , and the sensitivity and specificity were 86.84%and 81.82%respectively.The time-signal intensity curves of malignant tumors of mammary gland were mainly type III （70.27%）, while those of benign lesions of mammary gland were mainly type Ⅰ（73.91%）, and the difference was statistically significant （P〈0.05）.The early enhancement rate and peak enhancement rate of malignant tumors of mammary gland were both higher than those of benign lesions of mammary gland , and the differences were statistically significant （ P〈0.05） .Conclusion：Dynamic contrast enhanced MRI can manifest the morphologic and hemodynamic characteristics of breast lump , has comparatively high sensitivity and specificity , and can provide important foundations for qualitative diagnosis and therapy of diseases of mammary gland .
